I'm looking at a mint state coin that has at least 2 seperate strong die clashes. The coin looks MS65 + to me. Do the die clashes make the coin worth more or less in high mint states? Will anyone slab it with die clash notation? No pics till the auction is over, sorry. The coin may actually be as high as MS68 if all the marks correspond to the die clash.
Coins with die clash marks are slabbed all the time. As to value, that depends on a lot of variables.
