Seeriously Fake

I work in a pawn shop. A customer is trying to sell them some “ancient coins”.

Me: “I can’t take these coins.”

Customer: “Why not?”

Me: “They’re fake.”

Customer: “How can you tell! You can’t know that.”

Me: “They’re dated 100 BC.”

Customer: “Yeah, that means they’re really old.”

Me: “Are you really going to make me explain why I’m dubious about buying a coin apparently minted by someone who knew that Christ was coming a hundred years before he was born?”

Customer: “…you could sell them as prophetic coins!”

Me: “Please leave.”
