Haha, that $666 price for a G4 is definitely a twisted sign! It's painful to see people throwing $400 at this 'drunken date' variety. Real bidders or shill bidding, either way, it's a circus. Let's see if the auctioneer does the right thing!
They refused to pull it, even after I sent an image of a genuine one. Please bombard them with emails at office@bauerauction.com. Here is the listing: https://hibid.com/lot/313157578/key-date-1877-indian-head-cent-well-struck
Not a "like" for the auction, but thank you for naming and shaming. If the sellers can't be convinced that this is a fake, they have no business at all dealing in coins. And if they know it's a fake but still won't take it down, then doubly so.
