Proof Like (PL) designation 0

[theGr8Alexander]

This is a two fold question, when did NGC first use the PL and DMPL designations, and what is the criteria for a PL designation? How stringent is the PL eligibility?  What is the distinction between a PL coin and one that doesn’t make the cut?

Hello @theGr8Alexander, thank you for contacting NGC. 

Prooflike and Deep Prooflike designations were expanded to all US and World coins that merit them in 2003. While I cannot share specifics of our proprietary grading processes, I can share some general information about these designations. When a circulation issue coin’s fields exhibit a higher-than-normal degree of reflectivity, the coin is said to be “Prooflike” (or “PL”) because it is reminiscent of a Proof coin. If the fields are deeply mirrored, the coin is said to be “Deep Prooflike” (or “DPL”).

NGC uses the PL or DPL modifiers after an MS coin’s numeric grade, when applicable. These designations indicate only the degree of reflectivity evident in a coin’s fields and make no implication as to other qualities associated with Proof coins, such as frosted devices and superior sharpness. Kindly keep in mind that final designations for all graded coins are at the discretion of the graders. 

Please let us know if you have any additional questions. Thank you!
