Reference to the Coins Christian Symbol in the Bible
The Easton Bible Dictionary provides the following definition, meaning and reference to coins in the Bible.
Before the Exile the Jews had no regularly stamped money. They made use of uncoined shekels or talents of silver, which they weighed out (Gen. 23:16; Ex. 38:24; 2 Sam. 18:12). Probably the silver ingots used in the time of Abraham may have been of a fixed weight, which was in some way indicated on them.
The "pieces of silver" paid by Abimelech to Abraham (Gen. 20:16), and those also for which Joseph was sold (37:28), were probably in the form of rings.
The shekel was the common standard of weight and value among the Hebrews down to the time of the Captivity. Only once is a shekel of gold mentioned (1 Chr. 21:25). The "six thousand of gold" mentioned in the transaction between Naaman and Gehazi (2 Kings 5:5) were probably so many shekels of gold. The "piece of money" mentioned in Job 42:11; Gen. 33:19 (marg., "lambs") was the Hebrew _kesitah_, probably an uncoined piece of silver of a certain weight in the form of a sheep or lamb, or perhaps having on it such an impression. The same Hebrew word is used in Josh. 24:32, which is rendered by Wickliffe "an hundred yonge scheep."
