This article is a collection of Numismatic and coin collecting terms with concise explanation for the beginner or professional. Numismatics (ancient Greek: ) is the scientific study of money and its history in all its varied forms. While numismatists are often characterized as studying coins, the discipline also includes the study of banknotes, stock certificates, medals, medallions, and tokens (also referred to as Exonumia). Sub-fields or related fields of numismatics are: ; Exonumia: is the study of coin-like objects such as token coins and medals, and other items used in place of legal currency or for commemoration. ; Notaphily : is the study of paper money or banknotes. ; Scripophily : is the study and collection of stocks and bonds. ==A== ; Adjustment : The filing down of a blank to the correct weight before striking, shown by file marks. File marks are often still visible on the surface of a coin even after being struck. ; Alliance coinage : Coins minted by two or more state governments in conjunction. The Euro coins would be an example of this. ; Alloy : Homogeneous mixture of two or more elements, where the resulting compound has metallic properties. Common coin alloys include cupro-nickel (copper and nickel) and bronze (copper and tin). ; Altered Date : False date put on a coin to defraud collectors, usually to make it appear more valuable. Such alterations are often easily spotted with the aid of a magnifying glass. ; Anepigraphic coin : Coin without an inscription. Many ancient coins used only a simple picture of an animal to show value or weight. ; Annealing : Process of heating and cooling metal in order to relieve stresses. This is often done with coin blanks to make the metal less brittle before striking. ; Assay : Test to ascertain the weight and purity of a coin. ; Attribution : Identifier of a coin such as date, mint, denomination, or variety. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Glossary of numismatics」の詳細全文を読む スポンサード リンク
