Is the weight 2.5 grams? If so then probably just a plating blister, otherwise maybe a die chip for 3.11 grams. But I'd guess a plating blister by the looks of it
It's a Large Date.. What does it weigh? If 2.5 grams thats a plating issue on the 2 If 3.11 grams it could be a Die Chip @Clawcoins we were thinking the same thing at the same time!
