Got this Quarter in pocket change and it has a crack from edge to edge on the reverse and what appears to be a crack on the obverse. These cracks look like planchet errors but not sure. Part of the plating is missing also.
Also, looks like some sort of gunk on the quarter, my guess would be gum or something like that but not sure. Tried soak in acetone to loosen it up but it's not coming off.
