What does dmpl mean in coin grading?

In coin grading, "DMPL" stands for "Deep Mirror Prooflike." It is a designation used to describe coins that exhibit a high degree of reflectivity in their fields, resembling the appearance of a proof coin, but with additional depth in the mirrors. To qualify as DMPL, the coin must have a strong contrast between the deeply mirrored fields and the frosted devices, which enhances its visual appeal and value. This grading is particularly significant for coins that are not officially minted as proofs.
