For five years I was holding 2 rolls of UNCIRCULATED nickels. The only reason I hold them was because Some of them have Extra Material. Now....... look that pretty 2. Thank for your opinion.
The ST looks like splits also, is that real life or just the photo? And a die crack, lucky slug. Is that left side of the reverse a greaser?
It looks like the 2 may have some tiny die chips on it. when chips break away from the die the spaces gets filled in when the coin is struck , this gives coins the appearance of having extra metal.
And "some times" the appearance of Double Die Also. Thinking slow the conclusion is. THERE'S NO XTRA MAT in any coin. If it is Xtra Mat. FROM WHERE IS COMING FROM?
