[KINGSCARD]

hi everyone just wondering in any one can find any info on this. for some reason crosby has 2 versions of the significant numbers dual jersey auto/87. 1 card is sn-sc and there not redemptions and there is a redemption card for the same significant numbers dual jersey auto /87 but its card sn-sb can anyone help me figure it out, please let me know what the redemption is for and if its different it might just be 2 sets of the same auto jersey insert numbered to 87 by why the redemption and multiple sets #d to 87 i didn't see any other player with 2 cards under significant numbers thank you.

the card # is usually the players name initals like if your name was bob smith your card would be sn-bs and they only have one but i cant find out why crosby has 1 numbered sn-sb and his initials sn-sc
