Found this in some rolls I was searching! I'm guessing die cap error, but i'm not sure!Any help would be appreciated!
A grease filled die. As far as I know, they don't carry a premium, unless you find a grease filled die collector. A weak strike is also possible, or a combination of the 2.
I would say struck through grease. With the coin being in a holder obscuring part of the rim it's hard to say for sure but what I can see looks to be fairly high rims indicating it being struck through not a weak strike. Just my opinion though.
