Quarter with a nice error

This is the 2016 Harpers ferry John Brown's fort and it's just supposed to be there with my post and everything but there's not supposed to be a person at the end of the building and your right hand side this one if you look carefully I got close enough to it you'll see the person I've checked every quarter I've ever come across that was a Harpers ferry 2016 and I've never seen that again I'm sure there might be something out there but this one so far the only one I've seen and I've had to send different sites to see if people seen anything like it and no one has so this ain't going to be a cheap one to buy well sort of I'll be open to offers .. look for the initials of the engraver p m. If you buy this, I'll give you a buffalo nickel and the piece of silver. Piece of silver is that small coin up there that I got pictures of 999 pure silver 1. G. The other picture is the Buffalo nickel
