Along with the new design process of the Presedential dollar series, comes new errors!
The new process involves a separate die to create the lettering on the edge of the new coins. Some coins have already been found in circulation that never made it through the edge-lettering die, therefore lacking the date, mintmark, and motto on the edge. Others have been found with strongly doubled-lettering. Keep your eye out for these new and interesting errors, as well as other possible undiscovered errors on the new presedential dollar series!
