I would say this is a contemporary counterfeit rather than a modern fake. Still fairly collectable, but not to the tune of $575!
The seller, who makes themself out to be a bit of a coin expert, probably should have made that clear in the description.
A 1911 proof coin I have. In hand it looks good but the photo I took shows evidence of much cleaning. Just goes to show how you can be deceived. The coin didn't cost a lot that probably reflects its condition. Caveat Emptor.
