Die Polish lines, Proof-Like designations and grading - some questions and thoughts ...
I ran across a nice MS67 Merc recently. The coin had significant die polishing lines and was described by its owner as proof-like. It got me wondering:
Does the presence of die polishing lines preclude a proof-like designation? After all, technically dpl's are "flaws" in the die and result in "imperfections" on the coin. It would seem to me the hairline, raised ripples/lines that result from dpl's would by definition preclude a mirrored, flat, polished field. But I guess you could argue that aside from a new die, a just polished die might stand the best chance of obtaining a PL look.
As far as grading is concerned, is die polishing a positive, neutral or negative? Again, I'm thinking the hairline scratches in the die and the raised lines that result are not the intended effect. Maybe the market (and tpgs?) are willing to look past these small imperfections since they are a result of the normal minting process and are fairly common? Maybe die polishing can be a case of market-acceptable - some of the rainfall/wood-grain/frosty effects are viewed as attractive and desirable?
Or is it something else altogether? I'm curious as to what other folks think. Many thanks.
If we were all the same, the world would be an incredibly boring place.
