T206 1/1

[swarmee]

Well, they're considered stamped buybacks. Of course there are thousands of these cards that are unstamped. But Topps included these as a chase insert in a set which sold 20,000+ packs at $15 each. They might have only inserted 10-20 original T206s with these 1/1 stamps in the entire print run. So it might have taken opening 1000 packs in order to get one of these. It doesn't make it worth thousands, but I could easily see them selling for 5-10x what a regular common in VG shape would cost.
1/1 stamped cards in this release made a couple of weeks ago are selling for $500 each. Many of these collectors have never held a T206. But the ones that get a real T206 card in their packs may sell it, or it may become the first of many in their collection.
