To me, the last digit of the date is a different font and the denticles don't seem right, as many are faded out, I guess to show wear. There's lots of entries if you google 1798 US dollar for just about the cost of shipping or less.
Clearly a fake to me. Lots of things wrong with it if you compare with at a real one. Craigslist is even more risky than ebay.
Red flags. 1. Looks fake. 2. Even if it wasn't fake, it looks harshly cleaned. 3. It's on... Craigslist.
I also thought fake immediately, and the cleaning is a way to hide that. Even if it is real what is it worth $3000? My spider sense says it is counterfeit.
