Some of these buybacks are a bit silly

Overall I think those stamps take away from the card itself, not a huge fan of them.

I believe it was last year when Topps put out their Topps 206 set, they inserted real T206 cards randomly in packs/boxes and at least two that I saw were serial numbered 1/1. Keep in mind that these were just common T206 cards with common backs. I don't know what they ended up selling for but one seller had his listed for $3,000 on ebay, for a T206 common, that Topps just imprinted a serial number. Made no sense to me and I would consider that a flaw on the card.

Back in 2004 or something I broke open a couple of boxes of the Topps Cracker Jack sets and was lucky enough to pull an actual Cracker Jack card though I can't remember if it was '14 or '15. There was no added stamp or anything done to it, it was just in a pack. In my opinion that's how it should be done.
