[QUOTE="physics-fan3.14, post: 4021042, member: 19165"]Yes, I think it is clearly PL. In the Heritage sale of the Bagne collection, they described this coin as "Strongly reflective with a touch of cartwheel luster on the obverse and a distinct halo effect on the reverse." As for the Pop 2: the PL effect on a die does not last for very long. Some dies last longer, and if it starts as a very deep mirrored prooflike you'll get more strikes before it is no longer PL. Modern dies have a polished chrome finish to prolong the life of the die, and these will strike many more PLs than classic dies like this Cincinnati. It is likely that, out of the 5,000 coins struck, less than a hundred had prooflike or semi-prooflike surfaces. So, the mirrors don't usually last long on a die. Combine this with, many coins were not saved or stored appropriately, so a few of the PL coins might now be damaged, cleaned, circulated, or otherwise impaired. There's also always a chance that there might be some examples out there which have never been submitted. For many, many of the issues known in PL (classic commems, Merc dimes, Washington quarters, etc), there are less than 5 designated for that date.[/QUOTE]
