Artist Proof - are AP's more desireable than the regular pin?
Think of AP's and PP's as first runs, in that regard they are going to be better in quality but it'll vary on the pin. I happened on an AP of an HM opin house pin I had and the lettering/detail was sharper then the rack version. Does it make it any more valuable, probably not by much unless you collect them but it is cool if you happen across one...
