PL and DMPL/DPL Morgan Dollars and Other Issues

You will see throughout our auctions that certain Morgan Dollars will have the grade MS-64 PL or MS-66 DMPL. The PL designation is used by all grading services to denote the coin has Proof-like characteristics, even though the coin is a business strike issue and issued for circulation. DMPL or DPL takes the appearance one step further and denotes that the coin has Deep Mirror Proof-like surfaces.
Note: DMPL and DPL are the same designation. DMPL is used by PCGS and ANACS, while NGC uses DPL.
You will see from our photographs of DMPL/DPL coins that the appearance is almost like one of a mirror, and the fields of the coin sometimes exhibit a consistent dark look. PL and DMPL/DPL coins sell for a premium over general coin issues.
More recently, both grading services assign PL and DPL grades to the popular 2009 $20 Ultra High Relief issue as well as the America the Beautiful 5 oz. Silver coins.
