What's the Coin Used for Paying the Tax?

Jesus asked for a tribute coin to show his position on the tax issue. The inscription is going to speak of the divinity and worship of caesar as a divine god. So we would assume that one of the herodians produced the coin. i picture jesus like, reaching out, like winking at them, an like not winking is it's ok. But well, we know where you stand now. Thank you very much.
