Stater

Stater sta'-ter (stater): Used only once, Mt 17:27, where it is rendered by "piece of money" in the King James Version and "shekel" in the Revised Version (British and American). It was originally a standard Greek weight equal to two drachmas, but later it was used to designate the tetradrachma, and this is probably the coin referred to in the above passage.
