I consider the following Descriptive Coin Luster Reflectivity Categories Nomenclature Progressively Transitioning with increasing Reflectivity from Frosty to Ultra-DMPL for Silver Dollars and other coins.

Frosty —> Satiny —> Glossy —> Semi-Prooflike (SPL) —> Prooflike (PL) —> Deep Mirror Prooflike (DMPL) —> Ultra Deep Mirror Prooflike (UDM)
