In coin grading, DMPL stands for Deep Mirror Proof-Like.
It describes coins, particularly Morgan Dollars, that were struck for general circulation but exhibit an exceptionally deep, mirror-like reflectivity in their fields (the flat surfaces) and often have frosted devices (the raised design elements). This combination gives them an appearance very similar to that of a true Proof coin, even though they were intended for regular use.
- Deeply mirrored fields: The surface of the coin acts like a mirror, reflecting objects at a greater distance than regular Proof-Like (PL) coins.
- Frosted devices: The design elements (such as the bust of Liberty or the eagle on the reverse of a Morgan Dollar) often appear frosted, creating a striking contrast with the mirrored fields. This is also known as cameo contrast.
- Distinction from Proof coins: While similar in appearance, DMPL coins were produced for circulation and may show signs of handling, unlike true Proof coins which are specially struck and handled with extreme care.
- Rarity and value: DMPL coins are relatively rare because the highly reflective surfaces and frosted devices were typically achieved only during the very early strikes of a die. As the die wore down, these qualities faded. This rarity translates into higher values compared to regular business strikes.
- Aesthetics: Collectors are drawn to the exceptional beauty and visual appeal of DMPL coins, particularly the strong contrast between the fields and devices.
Note: Professional coin grading services like PCGS and NGC evaluate and designate coins as DMPL (sometimes denoted as DPL by NGC) based on specific criteria related to reflectivity and cameo contrast.
What is the meaning of Dmpl in PCGS?
From my experience, Population levels mentioned in this article are based on the PCGS report for June 2008. DMPL represents the abbreviation for Deep Mirror Proof-Like, and this designation is awarded to Morgan Dollars that possess a minimum of 4″ of clear reflection in the fields.
What do the letters mean in coin grading?
This changed to the letter grading system beginning with the lowest grade – Basal State (also Poor (PO)), then continuing Fair (Fr), About or Almost Good (AG), Good (G), Very Good (VG), Fine (F), Very Fine (VF), Extremely Fine (EF), Almost or About Uncirculated (AU), Uncirculated (Unc) and up to Brilliant Uncirculated …
What does DPL mean in coin grading?
Coins with highly mirrored fields may even be designated “DMPL” (Deep Mirror Proof-Like, sometimes shortened to “DPL” or Deep Proof-Like ). These designations are found mostly on Morgan Dollars, and are more desirable than non-PL coins.
