About Good This grade is given to a coin that falls short of Good. Only the main features (such as the Peripheral lettering, date, stars, etc.) of the coin are present in this grade or partially worn away. This grade is also sometimes referred to as grade AG-3.
About Uncirculated At first glance, these coins would appear Uncirculated but will show slight friction or slight wear when they are investigated closer. The grades given for them are AU50, 53, 55, or 58.
AbrasionsAny Area(s) of the coin where a foreign object or another coin has displaced metal in an abraded fashion.
AccumulationA miscellaneous grouping of coins, and should not be confused with a coin collection. Examples of these are a grouping of a particular type, date, or series. (Example: an accumulation–of coins with Swallows or a certain animal on.)
Adjustment Marks These are Pre-striking file marks usually found on gold/silver coins that were minted before 1840. After 1840 these are not seen due to the improvement of the striking process and that the filing was on the rim.
AG-3About Good (the Grade). The letter(3) refers to the corresponding numerical description. The lettering on the coin is readable, with some moderate-heavy wear in the rim.
AGWActual Gold Weight – This refers to the physical amount of pure gold in a coin, medal or bar. Any alloys are included in the gross weight of the gold coin but excluded when referring to the AGW. 22 Carat Gold coins do have a percentage of copper in them.
Album Friction Friction might be slight, due to rubbing on the high points – Similar to album slide marks.
Album Slide MarksLines, due to the surface of a coin by the plastic partition of an album.
AlloyA mixture of two or more metals. Metals are sometimes mixed to make the coins more durable or a metal value less.
Almost UncirculatedOpposite of About Uncirculated.
Alteration Inclusion of date, mintmark, or other feature that has been changed, added or removed, usually to simulate a rarer issue. Example of this is the “99” over-stamped ZAR Kruger Pond which only 130 where produced.
American EagleThe United States Mint started in 1986 to sell silver bullion coins in the denomination of $1. The following year, they added a series of gold coins to the series and expanded it to 1/10, ¼, ½, and 1-ounce versions. On the reverse of each coin, a family of eagles is shown, hence the name.
ANAAmerican Numismatic Association – Founded in 1888 as a non-profit numismatic organization founded to promote numismatics.

preparation of the die or striking of the coin.
ANSAmerican Numismatic Society
Anvil Die The die upon which a planchet rests prior it get struck. Lower die refers usually to the reverse – although, on some issues with striking problems, the obverse was employed as the lower die. The fixed lower-die impression is in some cases better struck than the upper-die impression, due to the process of minting.
Archiving To file or collect
ArrowsNormally design element – Look at the left claw of the eagle seen on many United States coins.
Arrows and RaysRefers to the quarters and a half dollars of 1853. The rays were removed in 1854 – This was done due to the complexity of this design.

AU-50 , AU-53, AU-55, AU-58About Uncirculated(the grade) and50(the numerical designation of that grade). There are four AU grades. AU-50 is the lowest. The other grades are AU53, AU55, and AU58. High points of the coin will have wear that is easily noticeable to the naked eye. AU-58 shows the slightest wear on the high points, even though it may be necessary to tilt the coin towards the light source to see the friction.
AuctionAuctions are taking place every day and a very good example is ebay.com or bidorbuy. Coins are offered for sale – Buyers interested will look at picture and description and based on this, bid against other buyers. The price is not fixed.
AuthenticationThe process of determining the genuineness of a coin or numismatic item by inspecting it and using consistent methods.

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 BreakRaised irregular areas on a coin, the result of metal from the planchet being forced through a portion of the die which has broken and fallen out during the minting process. Dies are made of steel and they crack from use and have to be checked often. When the die breaks apart, the resultant break will result in a full, or retained, cud depending on whether the broken piece falls from the die or not.
Die CrackRaised, irregular lines on a coin, the result of a die having cracked and metal being forced through those cracks at the time of striking

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.

Double Edge Lettering-Overlap It 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 many 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 a doubling of design elements. When this doubled die is used and area or the entire devices of one side of the coin appears doubled.
Double(d)-DieJargon 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 to sharpen their details; this is sometimes only visible under magnification.

This provided not only a guarantee of authenticity but also provided a space for a description that could be useful in cases of stolen collections.
PO-1 This is for Poor(the grade) and1(the numerical designation that means Poor). A coin of this grade is basically uncollectible due to its terrible condition, could be rare, making them popular.
Polished Die A die that has been basined to remove clash marks or die injury. In a positive sense, Proof dies were basined to impart mirrorlike surfaces, resulting in coins with the reflective field.
Polyvinyl Chloride (PVC)A chemical used in coin flips to make them elastic. This chemical will damage coins if it comes into contact for long periods. The plastic flips that are used to store coins for long periods, contains PVC and not recommended.
PoorThe grade PO-1. A coin with the readable date and mintmark (if present), but little more, barely identifiable as to type.

Professional Numismatists GuildA dealer organization began in 1955. The membership is restricted by financial and longevity requirements.
Proof Specially polished dies are used to strike the designs onto specially prepared polished blanks. Sometimes more pressure is applied when striking these coins and the presses operate at slower speeds. These coins get a lot more attention and extra care. Proofs generally show much more detail than coins produced for circulating. Any coins prior to 1817 are recognized by the PCGS as Specimen Strikes (SP) and after 817 as Proofs (PR). Proof coins are not meant for circulation; they are for collectors and investors.
Proof SetA coin set containing Proof issues from a particular year. A few sets contain anomalies such as the 1804 dollar and eagle in 1834 presentation Proof sets.
Proof dies Specially prepared dies, often sandblasted or acid-picked, that are used to strike Proof coins. Often, the fields are highly polished to a mirrorlike finish, while the recessed areas are left “rough”; on coins struck with such dies, the devices are frosted and contrast with highly reflective fields. Matte, Roman, and Satin Proof dies are not polished to a mirror-like finish.
Proof-only issueA coin struck only in Proof, with no business-strike counterpart.

Racketeer Nickel A gold-plated 1883 No “CENTS” Liberty Head five-cent coin (“V” nickel). The story goes that a deaf-mute gold-plated these unfamiliar coins and would buy something for a nickel or less. Sometimes, he was given change for a five-dollar gold piece since the V on the reverse could be interpreted as either five cents or five dollars! (They have also been gold-plated since that time to sell to collectors.)

RedbookFirst issued in 1947, this yearly price guide has been the “bible” of printed numismatic retail price guides.
Reeded EdgeA term for the grooved notches on the edge of some coins. These were first imparted by the Mint’s edge machine, later in the minting process by the use of close collars – these sometimes called the third die or collar die. Reeded edge is the opposite to a smooth edge 😉

ReverseThe opposite side to obverse or tails side, of a coin. Generally the opposite of the date side.
RiddlerA machine used by mints that screens out planchets of the wrong size and shape prior to striking.
RimThe upraised area around the edges of both sides(obverse and reverse) of a coin.  The purpose of the rim is to make coins easy stackable, protects the coin’s design from damage and helps bring up the devices during the strike process.
Rim dingJargon for a rim nick.
Rim NickA term for a mark or indentation on the rim of a coin or other metallic numismatic item.
Ring Test A test used to determine whether a coin was struck or is an electrotype or cast copy. The coin in question is balanced on a finger and gently tapped with a metal object- a pen, another coin, and so on. Struck coins have a high-pitched ring or tone, while electrotypes and cast copies have little or none. This test is not infallible; some struck coins do not ring because of planchet defects such as cracks or gas occlusions; also, some cast copies have been filled with glass (or other substances) and do ring.
RipA numismatic purchase that is bought substantially below the price for which it can be resold.
RollA set number of coins “rolled up” in a coin wrapper. In old times, a roll meant the coins were rolled up in a paper wrapper, today they are likely to be slid into a plastic coin tube.
Roll frictionMinor displacement of metal, mainly on the high points, seen on coins stored in rolls.
Rolled EdgeA term is synonymous with rim (the raised edge around a coin). This has become part of the vernacular because of the Rolled Edge Indian Head eagle.
Rolled Edge Ten A common name for the Indian Head eagle struck as a regular issue with a mintage reported by some as 20,000, but according to official Mint correspondence, the figure was 31,550. However, some have considered it a pattern because all but 42 coins were reportedly melted. It is occasionally seen circulated but the average coin is Mint State 63 or higher.
Roller Marks Term to describe the mostly parallel incuse lines seen on some coins after striking. These were originally thought to be lines resulting from the debris “scoring” the metal strips before the blanks were cut. However, new research has pointed to the final step of strip preparation, the drawbar. To reduce the strips to the proper thickness, the final step was to pass them through the drawbar. It certainly seems logical that debris in the drawbar may cause these lines, if so, then draw-bar marks or lines would be a more appropriate term.
Roman Finish An experimental Proof surface used mainly on U.S. gold coins of 1909 and 1910. This is a hybrid surface with more reflectivity than Matte surfaces, but less than brilliant Proofs. The surface is slightly scaly, similar to that of Satin Proofs.

SacSacagawea Dollar
Sacagawea Dollar The Sacagawea dollar is a one-dollar value circulating coin that was introduced in the year 2000. It is also called the golden dollar in the non-numismatic community because of its colour. The coin honours Sacagawea, a Shoshone Indian woman who was a guide and interpreter for the Lewis and Clark expedition of 1804. Glenna Goodacre designed the obverse of the coin and Thomas D. Rogers created the reverse. Sacagawea dollars are struck for circulation at the Philadelphia and Denver Mints, while Proofs are struck in San Francisco.
Saint Slang for the Saint-Gaudens inspired double eagle struck from 1907 until 1933. (The 1933 issue is currently considered illegal to own as the government insists that none of this date was legally released.) This low relief copy of the Extremely High Relief and High Relief designs was the work of Chief Engraver Charles Barber.
Saint-Gaudens Last name of Augustus Saint-Gaudens, the preeminent sculptor of the late nineteenth and early twentieth century. At the request of President Teddy Roosevelt, he redesigned the eagle and double eagle in 1907 although he died mid-production. Also, slang for the Liberty Head double eagle or Saint.
Saltwater Unc A very deceptive term. Generally, a term to describe coins with a finely pitted surface, however, recent discoveries of coins that have been exposed to saltwater for over a hundred years has made this term inaccurate, if not obsolete. The sand, not the saltwater, likely does the pitting on gold and silver coins in the ocean. A better term for these coins would be sandblasted UNC or sand-damaged UNC’s.
San Francisco Mint The United States branch Mint located in San Francisco, California that struck coins from 1854 until 1955. After closing as a Mint, it served as an assay office until it reopened as a coinage facility in 1965. This facility manufactures annual proof coin sets, manufactures silver proof coin sets and manufactures commemorative coins. This mint uses the “S” mintmark.
Satin FinishAnother of the experimental Proof surfaces used on U.S. gold coins after 1907. The dies were treated in some manner to create the silky surfaces imparted to the coins.
Satin LusterFine, silky lustre is seen on many business strike coins, especially copper and nickel issues. Almost no “cartwheel” effect is seen on coins with this type of lustre.
ScratchA detracting line that is more severe than a hairline. The size of a coin determines the point at which a line ceases to be viewed as a hairline and instead is regarded a scratch; the larger the coin, the greater the tolerance. A heavy scratch may result in a coin not being graded by PCGS.
Screw PressThe first type of coining press used at the U.S. Mint. Invented by Italian craftsman Donato Bramante, this press had a fixed anvil (or lower) die, with the hammer (or upper) die being attached to a rod with screw-like threads. When weighted arms attached to the rod were rotated, the screw mechanism quickly moved the rod with the die downward, striking the planchet placed into the lower die. The struck coin then was ejected and the process was repeated.

Shiny SpotsAreas on Matte, Roman, and Satin Proofs where the surface has been disturbed. On brilliant Proofs, dull spots appear where there are disturbances; on textured-surface coins such as Matte, Roman, and Satin Proofs, these disturbances create “shiny” spots.
Shotgun Rolls This term has two definitions. The first refers to rolls of coins that contain double the normal amount of coins in a roll. For instance, a shotgun roll of silver dollars contains 40 coins. The name derives from the length of the rolls being similar to the length of a shotgun shell. These double rolls were common and popular during the great roll boom of the 1960s. The second definition of shotgun roll refers to a paper-wrapped roll that is machine-crimped like the end of a shotgun shell.
ShowCommon term for a bourse or coin show.

Silver NickelJargon for the Wartime nickel.
Silver Plug On certain early American coins, a silver plug was inserted into a hole in the centre of the coin. This silver was then flattened out when it was struck. The plug added weight and value to the coin to align it with correct specifications.Examples:1792 Silver-Center CentSpecimen 1794 Silver Dollarvarieties of 1795 Silver Dollars.
Silver-Clad A term used for the Kennedy half dollar(1965 to 1970). Silver-Clad was made of 40% silver and 60% copper. The coins have two outer layers containing primarily silver (80%) are bonded to a core made primarily of copper (79%).

Universal Rarity Scale A collectables rarity information scale developed in 1998 by 21 major collectables experts in order to both define rarity within their individual markets and allow collectors and dealers from different collectables markets to more easily communicate with one another. The Universal Rarity Scale is a 10 point scale. The least rare collectable items are those where more than 10,000 examples are estimated to exist. These items are designated “UR1” and are described as “readily available.” The rarest items are those where only one example is known to exist. These rarities are designated “UR10” and are described as “unique.”
UpgradeRefers to a coin being resubmitted to one of the third-party CERTIFICATION SERVICES and being returned in a higher grade. As the certified grade of a coin plays such a large role in determining its value, a one-point upgrade on the SHELDON scale could mean a significant increase in value.
