PCGS standards for DMPL Morgan Dollars?

Could someone give me a link to PCGS standards for Morgan Dollars that are designated deep mirror prooflike (DMPL).


Thanks,

PL show clear reflectivity at 2 to 4 inches. DMPL 6" or more without distortions. It's my understanding that they
use a ruller and place the coin at the end and see how far they can clearly read the mirrored reflection. If you
pick up the PCGS Official Guide to Coin Grading and counterfeit detection you can read all about it on pages
74 and 75. Hope that helps.

Moose: I think that you may find the following 2006 Deep Mirror Prooflike Morgan Dollar article by Mike DeFalco to be highly informative and interesting:

Is it true that ANACS's UDM standards are even higher? I've heard it said that any UDM coin would go DMPL at PCGS. Find it a little hard to believe.

I found this in the Coin Grading and Counterfeit Detection book: The easiest way to examine a coin for PL or DMPL status is to hold the coin perpendicular to a flat, white surface with either the writing or design across the item. The clarity of reflection, or lack thereof, will be obvious at this viewing angle. If there is fading or obscurity at the designated distances( 2 to 4 inches for PL and 6 inches for DMPL) , the coin with not attain PL or DMPL status.

The message in the Mike Defalco article seems to suggest that PCGS has move the dmpl limitation from 6 to 8.

I guess you really have to hope that your grader has solid 20/20 vision.

If prooflike is 2 to 4 and dmpl is 6-8 what happens to a coin that is 5 inches. We need to have a term for this level.

A semi prooflike is 1-2 inches.

DizzleCC: As PCGS has been getting more stringent in applying their DMPL Morgan Dollar designation (now 6-8 inches of reflectivity), they have effectively been designating coins as PL within the 4-6 inch reflectivity range, which moved the bar up on PL's at the lower end of qualification from 2-4 inches of reflectivity.

Tht's probably why it's now tougher to get either the DMPL or the PL designation on Morgan Dollars. Many of yesterday's DMPL's are today's PL's, while many of yesterday's PL's do not even qualify for that designation today.

For DMPL at PCGS, mirror reflectivity by itself is not enough. These days for the DMPL designation the coin also needs frosty devices. Basically it has to look like a cameo proof.

ANACS's UDM designation is for morgans with 12"+ reflectivity. I read that on their website some time ago and I don't know why PCGS and NGC don't use UDM too.

Below is another excellent article on Mirror Surface Morgans.

From Randy Campbell’s article:

At ANACS, the term PROOFLIKE refers to a coin with a minimum of two to four inches of reflectivity of standard typewriter printing in the fields on both sides of the coin. The term DEEP MIRROR PROOFLIKE (or "DMPL") refers to a coin with a minimum of four to six inches of reflectivity on both sides of the coin. At ANACS the term ULTRA DEEP MIRROR (or "UDM") refers to a coin with a minimum of 12 inches of reflectivity on both sides of the coins.


What are the standards that NGC uses to designate gold coins as PL? I have seen $20’s that appear to be strongly prooflike but lack the designation (even in comparison to $20’s labeled PL).

Does anyone know what the criteria are for PL and DPL labeling on double eagles? I believe they started adding this designation in early 2003.
