I was wondering if there was a way to identify which pin goes on to a card after it has been taken off. Is there a way to scan the barcode or some sort of database for the number on the sticker on the back? I have a ton of the old cards from when I collected as a kid and I want to put them back on the cards. Some of them I luckily labeled, but I have a whole stack more of them that I did not. I appreciate any help. Thanks!!!

I’ve just gotten back into pin trading and collecting after many years. I collected as a kid and these were some in my collection that I wanted to check out if they were real. I am fairly certain that the rockstar club penguin one is fake because of the back, but that is the only one that I am pretty sure of. Another one I am suspicious of is the Phineas and Ferb pin just because the boys look a little pale compared to a pin I know for sure is legit but maybe that is normal variations between different pins, not really sure. But any help that I could get would be great! Thanks!!!!
