'Drachma' in the Bible

Now [when] they arrived in Capernaum, the ones who collected the double drachma [tax] came up to Peter and said, "Does your teacher not pay the double drachma [tax]?"

Or what woman who has ten drachmas, if she loses one drachma, does not light a lamp and sweep the house and search carefully until she finds [it]?

And [when she] has found [it], she calls together [her] friends and neighbors, saying, 'Rejoice with me, because I have found the drachma that I had lost!'
