Anyone else receive an error in their 2017 silver proof coin set. I got the same quarter twice instead of 5 different ones. I'm just hoping that the set is not worth less because the US mint made a mistake. Any thoughts on this mistake?
This seems to be pretty common mint mistake, I have the 2000 mint sets both P & D with the same type of error. Not much of a premium, more or less what someone is willing to pay.
Anyone can remove one coin and replace it with another so it has absolutely zero premium. If anything I would say it is worth less.
