|Easton's Bible Dictionary|
Greek word rendered "piece of money" (Matthew 17:27, A.V.; and "shekel" in R.V.). It was equal to two didrachmas ("tribute money, 17:24), or four drachmas, and to about 2s. 6d. of our money. (see SHEKEL.)
Noah Webster's Dictionary
1. (n.) One who states.
2. (n.) The principal gold coin of ancient Greece. It varied much in value, the stater best known at Athens being worth about 1 2s., or about USD5.35. The Attic silver tetradrachm was in later times called stater.
Int. Standard Bible Encyclopedia
sta'-ter (stater): Used only once, Matthew 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.
