[QUOTE="foundinrolls, post: 103228, member: 4350"]Hi, I have yet to see a coin yet, especially on details this small, regardless of the depth of the detail that shows clear separations such as the ones I pointed out on anything but a coin with some die doubling. Since these coins, the 2003 and 2005 Proof Sacs, have doubling this clear on predominantly the designer's initials, the coins are likely ClassV (pivoted hub doubling) doubled dies. There is a long explanation as to how these Doubled Dies occur. Essentially, to make a long story short, doubling is evident opposite a pivot point near the edge of the coin opposite the doubling. I know, clear as mud and sounds like double talk. This form of doubling is caused when the die after its initial impression is mis-aligned with the hub a second time in a fan shape direction. The pivot point will usually be near the rim, and the doubling will be strongest opposite the pivot point. A good example of this doubling is the 1917 Lincoln cent doubled die obverse. The images on both these coins show a strong separation. If it was mechanical doubling on details that small, the metal would just be pushed around to such an extent that those depressions between the designer's initials would be non-existent. I am having a hard time being convinced, after having seen hundreds (maybe thousands) of doubled die coins that these coins are mechanically doubled. I really wish I could see these coins first hand :-) Thanks, Bill[/QUOTE]
