How come sometimes the obverse and reverse don line up?
How come sometimes the obverse and reverse don’t line up? I’ve seen a good number of coins where the obverse and reverse don’t line up. Obviously the front and back are upside down from each other, but sometimes you find a coin where it appears the top or bottom die must have shifted off center a few degrees. For example, you line the obverse of the coins up in your Dansco, but when you flip the page there are one or two coins that do not line up with the rest. How common is that and when did the US Mint implement sufficient quality controls to prevent it from happening? Is there a date after which if you find an off center coin that you assume it is an error, or a counterfeit? Thanks.
