I won this 1979-S Ty2 SBA from one of those sellers on ebay that certifiy there own coins. It had a PF70 DC grade to it but didn't say anything about the cracks at 5 oclock . This is the 3rd coin from this seller that didn't list it as an error.... Pics are from coin out of holder. Coins also looks to be dipped or other. I know I take a chance from buying from low tier slabbers but sometimes the rewards are great...well got to get back to my fishing hole I know theres a bigger one in there
Don't look like cracks to me, looks more like residue from the dipping that dried and left the contaminants on the surface.
