Fred,
SCD lists two variations for the 1962 Koufax so you might be able to get PSA to recognize if you send them the research. If they recognize it and grade it, then you would have to request it to be added to the registry.
The Mantle registry is correct for the dice card. Proof/test cards don't belong in the main registry. If someone were to request Battey be moved to Red it no doubt would be.
