[QUOTE="HawkeEye, post: 3118301, member: 86305"]This morning I posted a new MS66 coin with some very interesting features. [ATTACH=full]792880[/ATTACH] [url]http://www.stonemountainhalf.com/34289827_66.html[/url] The obverse is in really good shape and at first examination so is the reverse. But on closer study the reverse has some interesting features. 1. There is a die crack that runs down the eagle's left wing that we see on most coins, so probably a weak point in the design 2. There is letter doubling in several places on the reverse, but we believe some to be on the die and some potentially from the strike 3. We are looking into another common feature of this series and that is improper annealing/tempering of the dies. On the reverse many of the letters at the rim have a concave appearance where the die has collapsed and left an uneven impression. This needs more work, but we think this is the case. The dies were not prepared by the Mint, so it is certainly possible.[/QUOTE]
