Looking at my accumulation tonight I found 5 2007 P U S Mint Sets where the LMC's all have the same die cracks. One is across the entire head top to back and the other runs from the top to just above the eye. Coins in the mint package are difficult to photo. I think I did a pretty good job. I have several of the Denver Sets with identical die cracks on the Dime. For later. Comments are always welcome.
Opened another 2007 Mint Set and found the same Die Crack on the 2007 P LMC. That makes six coins from the same die.
