This is my first post and items may have discussed before. The elite 11 T206 cards come with both PIEDMONT 350 and EPDG backs. It appears from my limited evaluation of EBAY listing that PIEDMONT 350 backs sell for considerably more money than EPDG backs. From just the PSA population report some items are much rarer with PIEDMONT 350 backs like Mullin ( 4 PIEDMONT 13 EPDG) and Spencer (1 PIEDMONT 9 EPDG) . However some cards are the nearly the same rarity level and in the case of Ganley ( 7 PIEDMONT 5 EPDG) it is scarer with the EPDG back yet the Piedmont 350 appears to sell for more. I realize this is a small sample size. Has anyone done a detail evaluation of the relative scarcity of these back from grading services population reports, auctions, EBAY etc?
I am also curious why Al Shaw was not included in the elite 11 group.
