'Coin' in the Bible

"Aren't two sparrows sold for an assarion coin? Not one of them falls on the ground apart from your Father's will,

“But, so we won’t offend them, go to the sea, cast in a fishhook, and take the first fish that you catch. When you open its mouth you’ll find a coin. Take it and give it to them for Me and you.”

Show Me the coin used for the tax.” So they brought Him a denarius.
