It's a fake cast copy. Unfortunately for him/her, and they may have not done it, but they certainly don't know any better; as you suggested, they don't sell coins much; they chose the rarer of the bunch. CURRENCY is spelled with 1 R. These are much rarer than the ones with 2 R's. Actually there are only 2 known with 1 R that were made of silver. That is one idea, you could e-mail them and ask what it is made of? See what they come back with, that would be interesting. There are only 2 known made of silver with 2 R's also. The rest were made of pewter and brass. These are $7,500 dollar coins and the silver ones, well, far out of any of our reaches. The last time one sold it went for $345,000. It certainly didn't sell for $24.05. It has been my experience, if something looks to good to be true, it usually is.
