You won't get the same card back. They would get you a whole new card. Meaning you wouldn't have the same patch or anything. Only thing that would remail is the serial number. Also Did you try looking under the other shoe or firesuit? In Total Memorabilia sheet metal did become dislodged and slid under the other stuff.
I cannot see it not being in there as the card would be damaged if it was taken out. And they use a double sided tape adhesive to secure the pieces. I can't see it being 4 colors like that as HellsBells pointed out. And sheet metal will sit lower as it's thinner than the memorabilia. You can tap it with a pin or some other metal object. You can tell the difference between metal on metal and metal on cardboard.
And looking at your pics I still say its metal.
