'Penny' in the Bible

He charged them to take nothing for the journey except a stick; no bread, no bag, and not a penny in their pockets,

Shall we give, or shall we not give? But he, knowing their hypocrisy, said unto them, Why tempt ye me? bring me a penny, that I may see it.

And a poor widow came and put in two small copper coins, worth less than a penny.
