Numismatic Lexicon: C – D

C
Mintmark used to signify coins struck at the Charlotte, North Carolina branch Mint.

C-Mint
Term applied to the gold coins struck at the Charlotte, North Carolina branch Mint. This Mint only struck gold coins from its opening in late 1837 until its seizure by the Confederacy. (Those coins struck in late 1837 were dated 1838.)

CA
Short for Cameo.

Cabinet friction
Slight disturbance seen on coins (usually on the obverse) that were stored in wooden cabinets used by early collectors to house their specimens. Often a soft cloth was used to wipe away dust, causing light hairlines or friction.

CAM
Short for Cameo. Also, PCGS grading suffix used for 1950 and later Proofs that meet cameo standards.

Cameo
The term applied to coins, usually Proofs and prooflike coins, that have frosted devices and lettering that contrast with the fields. When this is deep the coins are said to be “black and white” cameos. Occasionally frosty coins have “cameo” devices though they obviously do not contrast as dramatically with the fields as the cameo devices of Proofs do. Specifically applied by PCGS to those 1950 and later Proofs that meet cameo standards (CAM).

Canadian
Slang for the coins and other numismatic items of the Canada.

Canadian silver
Slang for the silver coins of Canada. (Mainly struck in 80% fineness.)

Cap Bust
Alternate form of Capped Bust

Capped Bust
A term describing any of the various incarnations of the head of Miss Liberty represented on early U.S. coins by a bust with a floppy cap. This design is credited to John Reich.

Capped die
The term applied to an error in which a coin gets jammed in the coining press and remains for successive strikes, eventually forming a “cap” either on the upper or lower die. These are sometimes spectacular with the “cap” often many times taller than a normal coin.

Carbon spot
A spot seen mainly on copper and gold coins, though also occasionally found on U.S. nickel coins (which are 75 percent copper) and silver coins (which are 10 percent copper). Carbon spots are brown to black spots of oxidation that range from minor to severe – some so large and far advanced that the coin is not graded because of environmental damage.

Carson City Mint
Located in Nevada, this mint produced gold and silver coins from 1870-1893. It was closed from 1885-1889 due to a lack of funding. In 1893 the mint was permanently closed due to internal corruption. In 1895 it was found that several employees and prominent community officials were stealing bullion from the mint and this dashed all hopes of the mint ever reopening. Coins minted in Carson City are among the most popular branch-mint issues. This mint uses the “CC” mintmark.

Cartwheel
The pleasing effect seen on some coins when they are rotated in a good light source. The luster rotates around like the spokes of a wagon wheel. A term applied mainly to frosty Mint State coins, especially silver dollars, to describe their luster. Also, a slang term for a silver dollar.

Cast blanks
Planchets made by a mold method, rather than being cut from strips of metal.

Cast counterfeit
A replication of a genuine coin usually created by making molds of the obverse and reverse, then casting base metal in the molds. A seam is usually visible on the edge unless it has been ground away.

Castaing machine
A device invented by French engineer Jean Castaing, which added the edge lettering and devices to early U.S. coins before they were struck. This machine was used until close collar dies were introduced which applied the edge device in the striking process.

Catalog
A printed listing of coins for sale either by auction or private treaty. As a verb, to write the description of the numismatic items offered.

CC
Mintmark used to signify coins struck at the Carson City, Nevada branch Mint.

CC-mint
Term applied to coins struck at the Carson City, Nevada branch Mint.

Chapman Proof
Those 1921 Morgan dollar Proofs supposedly struck for coin dealer Henry Chapman. These have cameo devices and deeply mirrored surfaces like most Morgan dollar Proofs. (George Morgan did bill Henry Chapman for 10 Proof Morgan dollars in 1921. Possibly, more coins from these dies were struck for others as there apparently more known than ten.)

Charlotte Mint

A method used by forgers to create a mint mark on a coin. It involves heating the surfaces and moving the metal to form the mint mark.

Cheerios Dollar
One of 5,500 2000-P Sacagawea Dollars placed along with a 2000-P Lincoln Cent in boxes of Cheerios cereal to promote the new Dollar coin. Some design details on the "Cheerios" Dollars are different from later strikes, causing some experts to propose the "Cheerios" Dollar as a pattern coin.

Choice
An adjectival description applied to coin's grade, e.g., choice Uncirculated, choice Very Fine, etc. Used to describe an especially attractive example of a particular grade.

Choice Unc
Short for Choice Uncirculated.

Choice Uncirculated

Clad bag
Usually applied to a one-thousand dollar bag of 40-percent silver half dollars although it also could apply to any bag of “sandwich” coins.

Clash marks
The images of the dies seen on coins struck from clashed dies. The obverse will have images from the reverse and vice versa.

Clashed dies
Dies that have been damaged by striking each other without a planchet between them. Typically, this imparts part of the obverse image to the reverse die and vice versa.

Classic Era
The term describing the period from 1792 until 1964 when silver and gold coins of the United States were issued. (Gold coins, of course, were not minted after 1933.)

Classic Head
A depiction of Miss Liberty that recalls the “classic” look of a Roman or Greek athlete wearing a ribbon around the hair. The motif was first used on the John Reich designed large cent struck from 1808 until 1814. The next year, the half cent was changed to this design. This head was also copied by William Kneass for the quarter eagle and half eagle designs first struck in 1834.

Cleaned
A term applied to a coin whose original surface has been removed. The effects may be slight or severe, depending on the method used.

Clip
Slang for a coin struck from a clipped planchet.

Clipped
A term for an irregularly cut planchet. A clip can be straight or curved, depending upon where it was cut from the strip of metal.

Clogged die
A die that has grease or some other contaminant lodged in the recessed areas. Coins struck from such a die have diminished detail, sometimes completely missing.

Collar
A metal piece that either positions a planchet beneath the dies and/or restrains the expanding metal of a coin during striking. Collars are considered the “third” die and, today, are used to impart the edge markings to a coin. Collars can be merely a hole in a flat piece of metal or a set of segments that pull away from the coin after it is struck.

Collection
Short for “coin collection.”

Collector
An individual who amasses a systematic group of coins or other numismatic items.

Commem
Short for “commemorative.”

Coins issued to honor some person, place, or event and, in many instances, to raise funds for activities related to the theme. Sometimes called NCLT (non-circulating legal tender) commemoratives.

Commercial grade
A grade that is usually one level higher than the market grade; refers to a coin that is "pushed" a grade, such as an EF/AU coin (corresponding to 45+) sold as AU-50.

Commercial strike
A synonym for regular strike or business strike.

Common
A numismatic issue that is readily available. Since this is a relative term, no firm number can be used as a cut-off point between common and scarce.

Common date
A particular issue within a series that is readily available. No exact number can be used to determine which coins are common dates as this is relative to the mintage of the series. (i.e. A 1799 eagle is a common date within its series just as an 1881-S silver dollar is a common date within the Morgan series. Obviously, the 1799 eagle is rare compared to the 1881-S dollar.)

Complete set
A term for all possible coins within a series, all types, or all coins from a particular branch Mint. Examples would include a complete set of a series (The three-dollar series can have but one complete set, that being the Harry Bass Foundation set that includes the unique 1870-S. Yes, it is possible that the cornerstone coin could appear someday and change the unique status; a complete gold type set would include examples of all types from 1795 until 1933; a complete set of Charlotte Mint gold dollars must include the 1849-C Open Wreath example of which there are but four currently verified.)

Condition
The state of preservation of a particular numismatic issue.

Condition Census
A listing of the finest known examples of a particular issue. There is no fixed number of coins in a Condition Census with 5, 6, 10, and other totals used by different surveyors.

Consensus grading
The process of determining the condition of a coin by using multiple graders.

Contact marks
Marks on a coin that are incurred through contact with another coin or a foreign object. These are generally small, compared to other types of marks such as gouges.

Contemporary counterfeit
A coin, usually base metal, struck from crudely engraved dies and made to pass for face value at the time of its creation. Sometimes such counterfeits are collected along with the genuine coins, especially in the case of American Colonial issues.

Continental dollars
1776 dated “dollars” struck in pewter (scarce), brass (rare), copper (extremely rare) and silver (extremely rare). Although likely struck sometime later than 1776, these saw extensive circulation. The design was inspired by certain Benjamin Franklin sketches. Some of these were possibly struck as pattern “cents” instead of “dollars.”

Copper spot
A spot or stain commonly seen on gold coinage, indicating an area of copper concentration that has oxidized. Copper spots or stains range from tiny dots to large blotches.

Copper-nickel
The alloy (88% copper, 12% nickel) used for small cents from 1856 until mid-1864.

Copper-Nickel Cent
The cents issued from 1859 until 1864 in the copper-nickel alloy. These were called white cents by the citizens of the era because of their pale color compared to the red cents of the past.

Coppers
Slang for half cents, large cents, and pre-Federal copper issues.

Copy
Any reproduction, fraudulent or otherwise, of a coin.

Copy dies
Dies made at a later date, usually showing slight differences from the originals. Examples include the reverse of 1804 Class II and III silver dollars and 1831 half cents with the Type of 1840-57 reverse. Also used to denote counterfeit dies copied directly from a genuine coin.

Coronet Head
Alternate name for Braided Hair design by Christian Gobrecht (also called Liberty Head design).

Corrosion
Damage that results when reactive chemicals act upon metal. When toning ceases to be a "protective" coating and instead begins to damage a coin, corrosion is the cause. Usually confined to copper, nickel and silver regular issues, although patterns in aluminum, white metal, tin, etc., also are subject to this harmful process.

Cost
The price paid for a numismatic item.

Counterfeit
Literally, a coin that is not genuine. There are cast and struck counterfeits and the term is also applied to issues with added mint marks, altered dates, etc.

Counterstamp
A stamp or impression placed on a coin after it has left the Mint of origin. Counterstamps were frequently used as advertising gimmicks on Large Cents and other coins. The counterstamp leaves a permanent impression on the metal and may hurt the value of the coin. It may also help the value, as in the case of an Ephriam Brasher counterstamp.

Counting machine mark
A dense patch of lines caused by the rubber wheel of a counting machine where the wheel was set with insufficient spacing for the selected coin. Many coins have been subjected to counting machines – among these are Mercury dimes, Buffalo nickels, Walking Liberty half dollars, Morgan and Peace dollars, and Saint-Gaudens double eagles.

Crossover
A word that is used to describe a coin that graded the same at two different grading services. Also written as two words: cross over. "I was sure that the coin wouldn't cross over, so I didn't buy it." or "That coin's definitely a crossover."

CU3000
Short for Coin Universe 3000

Cud
An area of a coin struck by a die that has a complete break across part of its surface. A cud may be either a retained cud, where the faulty piece of the die is still in place, or a full cud, where the piece of the die has fallen away. Retained cuds usually have dentil detail if on the edge, while full cuds do not.

Cull
A coin that is basically non-collectible due to its extremely bad condition. A coin that will not even qualify for a grade of Poor-1, usually because of extensive environmental damage or other post-striking damage.

Cupro-nickel
Any alloy of copper and nickel. Now usually used in reference to the modern “sandwich” issues. The copper-nickel cents, three-cent nickel issues, and nickel issues are also cupro-nickel.

D
Mintmark used on gold coins of the Dahlonega, Georgia, Mint from 1838 to 1861 and on coins of all denominations struck at the Denver, Colorado, Mint from 1906 to the present.

D-Mint
Term used for the gold coinage struck at the branch Mint in Dahlonega, Georgia, from 1838 to 1861, and for the coinage struck at the branch Mint in Denver, Colorado, from 1906 to the present.

Dahlonega Mint
After the discovery of gold in the southern United States a new mint was constructed in Dahlonega, Georgia. The first coinage exited its doors in 1838 and it continued minting until it was closed due to the civil war in 1861. The 1861-D gold dollars were struck after the Mint was seized, the mintage figure for this rare issue is not listed in Mint records and has been estimated at 1,000 to 1,500 examples. The Dahlonega Mint struck only gold coins and used the “D” mintmark.

Date
The numerals on a coin representing the year in which it was struck. Restrikes are made in years subsequent to the one that appears on them. Also, slang for a more valuable issue within a series.

DC
Short for Deep Cameo.

DCAM
Short for Deep Cameo.

DDO
An acronym for Doubled Die Obverse.

Dealer
Someone whose occupation is buying, selling, and trading numismatic material.

Deep Cameo
The term applied to coins, usually Proofs and prooflike coins, that have deeply frosted devices and lettering that contrast with the fields - often called “black and white” cameos. Specifically applied to those 1950 and later Proofs that meet deep cameo standards (DCAM).

Deep mirror prooflike
Any coin that has deeply reflective mirror-like fields, the term especially applicable for Morgan dollars. Those Morgan dollars that meet PCGS standards are designated deep mirror prooflike (DMPL).

Denomination
The value assigned by a government to a specific coin.

Denticles
The tooth-like devices around the rim seen on many coins. Originally these are somewhat irregular, later much more uniform - the result of better preparatory and striking machinery.

Dentils
Short for denticles.

Denver Mint
The Denver Mint was established in 1906. It had formerly been an Assay Office since 1863. Today, this Mint manufactures coins of all denominations for general circulation, medals, coin dies, stores gold and silver bullion, manufactures uncirculated coin sets and commemorative coins. This mint uses the “D” mintmark.

Design
A particular motif on a coin or other numismatic item. The Seated Liberty, Barber, Morgan, etc. are examples of designs.

Design type
A specific motif placed upon coinage which may be used for several denominations and subtypes, e.g., the Liberty Seated design type used for silver coins from half dimes through dollars and various subtypes therein.

Designer
The individual responsible for a particular motif used for a numismatic series.

Device
Any specific design element. Often refers to the principal design element, such as the head of Miss Liberty.

Device punch
A steel rod with a raised device on the end used to punch the element into a working die. This technique was used before hubbed dies became the norm.

Die
A steel rod that is engraved, punched, or hubbed with devices, lettering, the date, and other emblems.

Die alignment
Term to indicate the relative position of the obverse and reverse dies. When the dies are out of alignment, several things can happen: If the dies are out of parallel, weakness may be noted in a quadrant of the coin's obverse and the corresponding part of the reverse; and if the dies are spaced improperly, the resultant coins may have overall weakness; if the dies are spaced too close together, the resultant coin may be well struck but the dies wear more quickly.

Die break
An area of a coin that is the result of a broken die. This may be triangular or other geometric shape. Dies are made of steel and they crack from use and then, if not removed from service, eventually break. When the die totally breaks apart, the resultant break will result in a full, or retained, cud depending whether the broken piece falls from the die or not.

Die crack
A raised, irregular line on a coin, ranging from very fine to very large, some quite irregular. These result when a hairline break occurs in a die.

Die line
These are the raised lines on the coins that result from the polish lines on the die, which are incuse, resulting in the raised lines on the coins.

Die rust
Rust that has accumulated on a die that was not stored properly. Often such rust was polished away, so that only the deeply recessed parts of the die still exhibited it. A few examples are known of coins that were struck with extremely rusted dies – the 1876-CC dime, for one.

Die stage
There are two definitions for this term. One, many numismatists use it as a synonym for "die state." Two, some numismatists use the term "die stage" to refer to the specific status of a certain die state. For instance, in die state XYZ this coin exhibits a large cud at six o'clock, but in this particular die stage the cud isn't fully formed.

Die state
A readily identified point in the life of a coinage die. Often dies clash and are polished, crack, break, etc., resulting in different stages of the die. These are called die states. Some coins have barely distinguishable die states, while others go through multiple distinctive ones.

Die striations
Raised lines on coins that were struck with polished dies. As more coins are struck with such dies, the striations become fainter until most disappear.

Die trial
A test striking of a particular die in a different metal.

Die variety
A coin that can be linked to a given set of dies because of characteristics possessed by those dies and mparted to the coin at the time it was struck. In the early years of U.S. coinage history, when dies were made by hand engraving or punching, each die was slightly different. The coins from these unique dies are die varieties and are collected in every denomination. By the 1840's, when dies were made by hubbing and therefore were more uniform, die varieties resulted mainly from variances in the size, shape, and positioning of the date and mintmark.

Die wear
Deterioration in a die caused by excessive use. This may evidence itself on coins produced with that die in a few indistinct letters or numerals or, in extreme cases, a loss of detail throughout the entire coin. Some coins, especially certain nickel issues, have a fuzzy, indistinct appearance even on Uncirculated examples.

Dime
The denomination, one tenth of a dollar, issued since 1796 by the United States.

Ding
Slang term for a small to medium size mark.

Dipped
A term applied to a coin that has been placed in a commercial "dip" solution, a mild acid wash that removes the toning from most coins. Some dip solutions employ other chemicals, such as bases, to accomplish a similar result. The first few layers of metal are removed with every dip, so coins repeatedly dipped will lose luster, hence the term "overdipped".

Dipping solution
Any of the commercial "dips" available on the market, usually acid-based.

Disme
The original spelling of dime, the s silent and thought to have been pronounced to rhyme with steam. (This variation was used in Mint documents until the 1830s and was officially changed by the Coinage Act of 1837.)

DMPL
Short for deep mirror prooflike.

DNC
Did Not Cross (you will still be charged the grading fees)

Doctored
Term used for a numismatic item that has been enhanced by chemical or other means. Usually, this is used in a derogatory way.

Dollar
The denomination, consisting of one hundred cents, authorized by the Mint Act of 1792. This is the anglicized spelling of the European Thaler and was used because of the world-wide acceptance of the Thaler and the Spanish Milled dollar or piece-of-eight.

Double Eagle
Literally two eagles, or twenty dollars. A twenty-dollar U.S. gold coin issued from 1850 through 1932. One gold double eagle dated 1849 is known and is part of the National Numismatic Collection at the Smithsonian Institution. Nearly half a million examples dated 1933 were struck by the U.S. Mint, but virtually all were melted when private gold ownership was outlawed that year. (Currently federal officials claim it is illegal to own any 1933-dated specimens that survive.)

Double Edge Lettering-Inverted
Is normally a coin sent through the edge lettering device a second time with one set of lettering upside down. It also includes doubling of any design element due to slippage of the edge lettering device, such as a P mintmark over the 9 of the date.

Double Edge Lettering-Overlap
Is normally a coin sent through the edge lettering device a second time with the lettering in the same direction. It also includes doubling of any design element due to slippage of the edge lettering device, such as a P mintmark over the 9 of the date.

Double(d) die
A die that has been struck more than once by a hub in misaligned positions, resulting in doubling of design elements. Before the introduction of hubbing, the individual elements of a coin's design were either engraved or punched into the die, so any doubling was limited to a specific element. With hubbed dies, multiple impressions are needed from the hub to make a single die with adequate detail. When shifting occurs in the alignment between the hub and the die, the die ends up with some of its features doubled – then imparts this doubling to every coin it strikes. The coins struck from such dies are called doubled-die errors – the most famous being the 1955 Doubled Die Lincoln cent. PCGS uses doubled die as the designation.

Double(d)-Die
Slang for the rare 1955 Doubled Die Lincoln Cent variety.

Double-struck
A condition that results when a coin is not ejected from the dies and is struck a second time. Such a coin is said to be double-struck. Triple-struck coins and other multiple strikings also are known. Proofs are usually double-struck on purpose in order to sharpen their details; this is sometimes visible under magnification.

DPG
Short For Daily Price Guide, specifically the Coin Universe Daily Price Guide

Draped Bust
The design attributed to Mint engraver Robert Scot that features Miss Liberty with a drape across her bust. Scot presumably copied the design after a portrait by Gilbert Stuart.

Drift mark
– An area on a coin, often rather long, that has a discolored, streaky look. This is the result of impurities or foreign matter in the dies. One theory is that burnt wood was rolled into the strips from which the planchets were cut, resulting in these black streaks.

Dull
Term for a numismatic item that is lack luster. This may be the result of cleaning, oxidation, or other environmental conditions.
