<p>[QUOTE="KurtS, post: 2104494, member: 11786"]What I find most interesting about this coin is how these marks seem to match details on the coin and cross what would be high-points on the die. In other words, if the final coin were an overstrike, we should expect to see design details of the prior strike preserved in the low points of the die--or high points on the coin. But here, we see marks that <i>should have been obliterated</i> by the second strike. For this reason, I suspect the marks were on the die itself--finding a match on another coin would be confirmation here. I do know in the IHC series there are several cases of off-center design details transferred to the die--the mechanism isn't fully understood. <b>Pure speculation here</b>--but perhaps they tapped the annealed die blank with the hub to check its softness prior to hubbing, and some of these marks were preserved?[/QUOTE]</p><p><br /></p>
