Pawn Stars

It was authenticated by Rick's expert. Rick paid just under the retail price. You can tell he really wanted the coin, but wasn't to happy about what he paid. The seller really stood his ground against Rick and only wavered at the last moment to close the deal. I'd say the seller won that round.

Who ever minted the coin, in my opinion, was not a big fan of Caligua and made him extremely ugly. On his bust, there are bags under his eyes and he was given a long pointy nose. Caligua's demise was met shortly after the coin was minted.

That's all I see when I click on Kelly's link. This episode hasn't screened here yet, so I can't see it. Sorry.

As for value, well, the only catalogue giving values for Caligula coins is now over 10 years old. And Caligula is both infamous and had a short reign, making his coins scarce to start with. Try looking here on acsearch for similar coins - or perhaps even the same coin, being sold previously.
