The Attic gold money was regulated according to the same standard of weight as the silver. The gold unit of account was, however, not the drachm, but the _stater_, as it was called, equivalent in weight to the didrachm, and in value to 20 drachms of silver. As a rule, the denomination of a Greek coin can only be determined by weighing it. Marks of value occur, however, on the copper of Italy, Sicily, etc.; but these coins follow a system foreign to Greece proper (see below). § OF THE ARRANGEMENT OF A CABINET OF GREEK COINS.
