'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, lest we cause them to stumble, go to the sea, cast a hook, and take up the first fish that comes up. When you have opened its mouth, you will find a stater coin. Take that, and give it to them for me and you."

A poor widow came, and she cast in two small brass coins, which equal a quadrans coin.

Or what woman, if she had ten drachma coins, if she lost one drachma coin, wouldn't light a lamp, sweep the house, and seek diligently until she found it?
