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.[dubiousdiscuss] Many objects have been used for centuries, such as cowry shells, precious metals, cocoa beans, large stones, and gems.

A silver tetradrachm of Ptolemy IV Philopator (r. 221 – 205 BC); an undated issue from the Arados royal mint, struck c. 214–212 BC, 26 mm in width, 14.10 gm in weight; the obverse shows a diademed head of Ptolemy I Soter wearing the aegis, while the reverse shows an eagle standing on a thunderbolt with a Greek inscription: ΠΤΟΛΕΜΑΙΟΥ ΣΩΤΗΡΟΣ, lit.'of Ptolemy Soter'.

Coinage of the Ptolemaic kingdom was struck in Phoenician weight, also known as Ptolemaic weight (about 14.2 grams) which was the weight of a Ptolemaic tetradrachm. This standard, which was not used elsewhere in the Hellenistic world, was smaller than the dominant Attic weight (about 17.28 grams) which was the weight of standard Hellenistic tetradrachm. Consequentially, Ptolemaic coins are smaller than other Hellenistic coinage. In terms of art, the coins, which were made of silver, followed the example set by contemporary Greek currencies, with dynastic figures being typically portrayed. The Ptolemaic coin making process often resulted in a central depression, similar to what can be found on Seleucid coinage.

The Ptolemaic dynasty introduced standard coinage to Egypt, where pre-existing native dynasties made only very limited use of coins. Egyptian gold stater was the first coin ever minted in ancient Egypt around 360 BC during the reign of pharaoh Teos of the 30th Dynasty. These coins were used to pay salaries of Greek mercenaries in his service. (Full article...)
