It is very hard to tell from the photo. Mirrored coins are determined by the distance that "text" can be read in the reflection. Different grading companies have different distances. Generally a DMPL is 6" of mirror depth. Jim
It is almost impossible for us to tell from photos if this coin is DMPL or not. You would have to measure the reflectivity yourself. Holding the coin upright, place it on top of a ruler and see how many inches you can read clearly in the reflection. As Jim said, 6" is pretty much standard, but I believe NGC & PCGS are a little stricter holding to this than is ANACS. Someone correct me if I'm wrong, but I seem to recall that more than 8" of reflectivity is considered UDMPL. They're very rare, and I would love to see or own one. The coin you've shown us is a Morgan silver dollar. There were 17,787,000 struck for this Philly Mint date. According to Q. David Bowers, the optimal collecting grade is MS65, and the certified population of DMPL's in all grades is 2300+. The Morgan dollar was struck 1878-1904 and then again in 1921 after legislation was passed authorizing the issuance of the Peace dollar. The production of the 1921 Peace dollar didn't begin until the last few days of December, 1921. Chris
ANACS is the only company of the big three that certifies UDMPL coins. I have one, it's a fantastic specimen.
Please correct me if I'm wrong, but doesn't ANACS use 4" or 5" as a minimum for DMPL? If so, what is their minimum reflective distance for UDMPL? Chris
