'Silver pieces' in the Bible

And Joab said to the man that told him, And behold, thou sawest him, and why didst thou not smite him there to the ground? and I would have given thee ten silver pieces and a girdle.

And the man said to Joab, Though I should receive a thousand silver pieces in my hand, yet would I not put forth my hand against the king's son; for in our hearing the king charged thee and Abishai and Ittai, saying, Take care, whoever it be of you, of the young man Absalom.
