[QUOTE="cdb1950, post: 40252, member: 1735"]I am assuming the area in question is the small dark area in the field above the buffalo. If the area is concave, recessed into the field of the coin, then you are right to conclude that it is not a die gouge. It must have been something between the coin and the die when it was struck, being a struck through coin. If it appears to have grinding marks under 10x magnification, then the grinding marks would have to have been imparted to the coin from the object on the die, or maybe the grinding marks could actually be rolling marks commonly found on coin blanks, especially nickel planchets. If the substance between the die and the planchet during the strike was grease or some other viscous material, then the original surface marks on the planchet would still be visible on the coin. A group of 11 might show evidence of progression, with the grease/object moving, spreading, or diminishing in size between strikes. Or it could be something else altogether. Need a close-up photo to be sure. Probably not worth a ton of money, but certainly interesting. Neat![/QUOTE]
