There also existed a "gold stater", but it was only minted in some places, and was mainly an accounting unit worth 20–28 drachmae depending on place and time, the Athenian unit being worth 20 drachmae. (The reason being that one gold stater generally weighed roughly , twice as much as a drachma, while the parity of gold to silver, after some variance, was established as 1:10). The use of gold staters in coinage seems mostly of Macedonian origin. The best known types of Greek gold staters are the 28-drachma "kyzikenoi" from Cyzicus.
