Card Identification Forum

This card is from the 2012 Panini Cooperstown set. It appears to be the base card (#57) with a sticker of the autograph and is stamped # 5 of 8. I have seen similar auto cards of other players all with very low print runs as follows: 

#16 - Rod Carew /2;

#23 - Barry Larkin /7;

#40 - Bill Mazeroski /9;

#57 – Phil Niekro /8;

#84 - Andre Dawson /10;

#92 - Stan Musial /6;

#107 - Rollie Fingers /19;

#118 - Orlando Cepeda /10;

#124 - Jim Palmer /18;

#125 - Monte Irvin /16;

#127 - Goose Gossage /17;

#135 - Brooks Robinson /9;

#138 - Johnny Bench /2;

#142 - Lou Brock /9;

#142 - Lou Brock /9;

#144 - Red Schoendienst /10;

#150 - Billy Williams /14;

They are on COMC as just base auto, but I don't think these cards came in the packs. I can't find info on where the come from.

I thought this sounded familiar so I went to the product's forum link and found this: https://www.tcdb.com/Forum.cfm/Page/S/ID/72733/?MODE=VIEW&ThreadID=26546&C=14. It looks like a bit more info was found but a checklist wasn't worked out yet.

If your list above are cards similar to Niekro (with sticker autos and stamped serial numbers) then that's a pretty good start to an unknown checklist we could probably add to later if more are discovered. Assuming we've checked the usual places 

They are the same as the Phil Niekro card shown (auto sticker and printed SN).

These were all that are currently for sale on Ebay.
