I have a set and one of the 3 proof cards, plus a wrapper and easel. About half of mine are graded, all PSA, but I am not a graded collector and just bought them that way. Would guess PSA would be best for value but others may differ. One reason for grading beyond value may be protection
Not sure which ones you have. Maloney and Fairly are the most common, although the dugout versions of both usually have a premium. The Clemente is the most expensive one to get in the set of 12. And there are degrees of scarcity for the others that affect value. The B Robinson prototype and the 3 proof cards are also very costly
And the backs can affect value. Some are blank and others have stamped backs that vary. Olbermann has an SCD article on the different front and back variants. Dave Hornish may also have an article on them on his blog. Will try to post links later
