1902-O $1, DMPL MS63DMPL 认证号07176738, PCGS号97281

Little to no contrast against the deep mirrors can been seen on both the obverse and reverse. Most 1902-O DMPL's and PL's show little contrast due to how the mint workman basined the dies and how fine a polishing compound was used in the last basining step.

In 2005, PCGS determined that all 1896-O, 1900-O and 1902-O Silver Dollars with so-called "Micro o" mintmarks were counterfeit. This announcement was based on the discovery that all three dates shared common die markers.
