'Pieces Of Silver' in the Bible

Then Joab said to the man who [was] telling him, "Look, [if] you saw, why did you not strike him down to the ground there? {I would have gladly given you} ten pieces of silver and a leather belt."

The man told Joab, “Even if I were to feel the weight of a thousand pieces of silver in my hands, I would not put out my hand against the king’s son; for we all heard the king command you, Abishai, and Ittai, saying, ‘Protect the young man Absalom, for my sake.’

But the king said to Araunah, "No, I insist on buying it from you! I will not offer to the Lord my God burnt sacrifices that cost me nothing." So David bought the threshing floor and the oxen for fifty pieces of silver.
