Coin Grading
Coin grading is the process of determining the grade or condition of a coin, one of the key factors in determining its value. A coin's grade is generally determined by six criteria: strike, preservation, luster, color, attractiveness, and occasionally the country/state in which they’re minted. Several grading systems have been developed. Certification services professionally grade coins for tiered fees. Overview A "grade" measures a coin's appearance. There are generally five main components which determine a coin's grade: strike, surface preservation, luster, coloration and eye appeal. Grading is subjective and even experts can disagree about the grade of a given coin. History U.S. coin grading has evolved over the years to a system of finer and finer grade distinctions. Originally, there were only two grades, new and used. This changed to the letter grading system beginning with the lowest grade – ''Basal State'' (also ''Poor'' (PO)), then continuing ''Fair'' (Fr), ''Abou ...

Numismatic Guaranty Corporation
Numismatic Guaranty Company (NGC) is an international third-party coin grading and certification service based in Sarasota, Florida. It has certified more than 50 million coins. NGC certification consists of authentication, grading, attribution, and encapsulation in clear plastic holders. NGC is a subsidiary of Certified Collectibles Group (CCG), which owns six collectible certification services and is in turn owned by Blackstone, a multibillion dollar New York City hedge fund. History NGC was founded in 1987 in Parsippany, N.J. as one of the first independent third-party coin grading companies. In 1995, NGC was named the official grading service of the ANA, though this is purely for marketing purposes as the ANA does not encapsulate coins in its collection, and those that are encapsulated are a mix of donated coins by different services including rivals such as PCGS. NGC commenced operations at its new location in Sarasota, Florida in 2002. That same year, NGC was named the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proof Coinage
Proof coinage refers to special early samples of a coin issue, historically made for checking the dies (as in demonstrating that something is true) and for archival purposes. Nowadays proofs are often struck in greater numbers specially for coin collectors (numismatists). Nearly all countries have issued proof coinage. Preparation of a proof striking usually involved polishing of the dies. They can usually be distinguished from normal circulation coins by their sharper rims and design, as well as much smoother "fields" – the blank areas not part of the coin's design. The dies for making modern proof coins are often treated with chemicals to make certain parts of the design take on a frosted appearance, with the polished fields taking on a mirror finish. Several other methods have been used in the past to achieve this effect, including sand blasting the dies, and matte proofs. Proof coins of the early 19th century even appear to be scratched, but it was part of the production ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exonumia
Exonumia are numismatic items (such as tokens, medals, or scrip) other than coins and paper money. This includes "Good For" tokens, badges, counterstamped coins, elongated coins, encased coins, souvenir medallions, tags, wooden nickels and other similar items. It is related to numismatics (concerned with coins which have been legal tender), and many coin collectors are also exonumists. Besides the above strict definition, others extend it to include non-coins which may or may not be legal tenders such as cheques, credit cards and similar paper. These can also be considered notaphily or scripophily. Etymology The noun ''exonumia'' is derived from two classical roots: ''exo'', meaning "out-of" in Greek, and ''nummus'', meaning "coin" in Latin (from Greek νοῦμμος – ''noummos'', "coin"); thus, "out ideof- he categoryoins". Usually, the term "exonumia" is applied to these objects in the United States, while the equivalent British term is paranumismatica. The words ''ex ...

Numismatics
Numismatics is the study or collection of currency, including coins, tokens, paper money, medals and related objects. Specialists, known as numismatists, are often characterized as students or collectors of coins, but the discipline also includes the broader study of money and other means of payment used to resolve debts and exchange goods. The earliest forms of money used by people are categorised by collectors as "Odd and Curious", but the use of other goods in barter exchange is excluded, even where used as a circulating currency (e.g., cigarettes or instant noodles in prison). As an example, the Kyrgyz people used horses as the principal currency unit, and gave small change in lambskins; the lambskins may be suitable for numismatic study, but the horses are not. Many objects have been used for centuries, such as cowry shells, precious metals, cocoa beans, large stones, and gems. Etymology First attested in English 1829, the word ''numismatics'' comes from the adjective ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paper Currency Grading
Paper currency grading is the process of determining the grade or condition of a bank note, one of the key factors in determining its value. A banknotes grade is generally determined by crispness (Rigid, not limp paper), brightness, and depth of color. Other factors that are taken into consideration include centering of the printed area, artificially suppressed folds, repairs, and pinholes. Certification services professionally grade banknotes for tiered fees. United States United States banknotes are graded by a system much like the 70 points Sheldon coin grading scale which is used for coins. Top-quality grades include "Gem" or "Choice" condition which is usually dubbed as "New" by sellers down to "poor" for notes barely identifiable. Paper money, in general, can become "ugly" over time which in turn affects eye appeal and value as it does with coins.

Coin Collecting
Coin collecting is the collecting of coins or other forms of minted legal tender. Coins of interest to collectors often include those that were in circulation for only a brief time, coins with mint errors, and especially beautiful or historically significant pieces. Coin collecting can be differentiated from numismatics, in that the latter is the systematic study of currency as a whole, though the two disciplines are closely interlinked. A coin's grade is a main determinant of its value. Commercial organizations offer grading services and will grade, authenticate, attribute, and encapsulate most coins. History People have hoarded coins for their bullion value for as long as coins have been minted. However, the collection of coins for their artistic value was a later development. Evidence from the archaeological and historical record of Ancient Rome and medieval Mesopotamia indicates that coins were collected and catalogued by scholars and state treasuries. It also seems pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cameo (coinage)
In coin grading, cameo is the amount of contrast between the relief (raised or recessed design) and field (background). Cameo is usually seen on proof coinage, with the relief featuring a frosted finish and the field being mirror-like. Not all proof coins have a cameo effect, however. History Cameos can be found on some of the earliest American proof coins, but have not been produced intentionally for the public until recently. The US Mint, like many mints around the world, now specifically sells cameo coins, which could previously only be found randomly in mint proof sets. Non-proof cameos Though rare, general circulation (non-proof) strikes may exhibit cameo as a result of die polishing. These coins are often designated "PL" (Proof-Like) if the cameo effect is strong enough. Coins with highly mirrored fields may even be designated "DMPL" (Deep Mirror Proof-Like, sometimes shortened to "DPL" or Deep Proof-Like). These designations are found mostly on Morgan Dollars, and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cleaning (coinage)
Coin cleaning is the process of removing undesirable substances from a coin's surface in order to make it more attractive to potential buyers. The subject is disputed among the numismatic community whether cleaning coins is necessary. Those that argue in favor of cleaning are also in dispute on which methods work best. It was once common practice to clean coins as the method was recommended by experts in the field. Solutions from pencil erasers to wire brushes and potassium cyanide were all used as cleaning agents with the goal to make the coin look brilliant again. When certified grading came into use in the mid 1980s though, the practice of cleaning coins diminished over time. Most coin experts have since come out against cleaning coins, as doing so can negatively affect them both in grade and value. If a potentially valuable coin must be cleaned (for example if the coin is deformed) then professional work is recommended. Commonly found coins are mentioned as ideal candidates for ...

Mint State
The Sheldon Coin Grading Scale is a 70-point coin grading scale used in the numismatic assessment of a coin's quality. The American Numismatic Association based its ''Official ANA Grading Standards'' in large part on the Sheldon scale. The scale was created by William Herbert Sheldon. Original Sheldon Scale (1949) In 1949, the original scale was first presented in "Dr. William H. Sheldon's Early American Cents" titled "A Quantitative Scale for condition" as a way to grade Large cents. The scale is known today as the Sheldon scale. Adapted scale (1970s–present) By 1953 the original Sheldon scale had become outdated. It was not until the 1970s, however, that the ANA chose to adapt the scale for use on all US coins. The scale used today is a modification of the original Sheldon scale, with added adjustments, additions, deletions, and modifications to it. ''Note'': Some early American coin varieties are almost always found to be weakly struck in places. This does not bring t ...

Franklin Half Dollar
The Franklin half dollar is a coin that was struck by the United States Mint from 1948 to 1963. The fifty-cent piece pictures Founding Father Benjamin Franklin on the obverse and the Liberty Bell on the reverse. A small eagle was placed to the right of the bell to fulfill the legal requirement that half dollars depict the figure of an eagle. Produced in 90 percent silver with a reeded edge, the coin was struck at the Philadelphia, Denver, and San Francisco mints. As of November 11, 2022, the melt value of the $0.50 coin was approximately $7.88. Mint director Nellie Tayloe Ross had long admired Franklin, and wanted him to be depicted on a coin. In 1947, she instructed her chief engraver, John R. Sinnock, to prepare designs for a Franklin half dollar. Sinnock's designs were based on his earlier work, but he died before their completion. The designs were completed by Sinnock's successor, Gilroy Roberts. The Mint submitted the new designs to the Commission of Fine Arts (" ...
