I found some information on the interweb about a claim that a
TPG swapped a resubmitted '64 SMS cent with a regular strike '64 cent. Some of the information in the report claims that the slab submitted for recertification was counterfeit or tampered with.
I can post the link to the report if anyone wants to take a look, but I wanted to see if it's been discussed on the CCF in the past before I do.
