We will see how this all plays out, and I expect to see fully private-key-loaded baseball cards coming in 2019 or 2020.
Those are some beautiful cards, and I hadn't seen this thread before--I half expected the crypto cards to be loaded with a nominal amount of bitcoin. It's great to see Topps do this, even though I don't collect cards anymore.I liked your brief history of the trading card bubble, and it was spot-on. Baseball was never my thing, but basketball was and those cards in 1986-88 (the ones I collected) didn't get printed nearly as much as baseball cards. By 1999, those TV marketing shows were selling boxes or cases of Upper Deck baseball cards with the Ken Griffey Jr. rookie in it. Very overpriced, too. It was crazy how people were speculating in sports cards of any kind. I used to subscribe to the Beckett monthly price guide, which was before the internet took off and it seems archaic nowadays that there were printed price guides.
Crazy how the quality of cards has gone up over the years, and it does seem like Topps and other companies have learned that overproducing cards screws collectors/investors. That's a huge positive. Unfortunately I don't think the younger generation is going to be all that excited about them. From what I've read of the current state of card collecting, most of the active collectors are middle-aged men--sort of like how most current stamp collectors are geriatric ones. Time will tell, but this is still very cool.

They said they do not have cases that large and unfortunately cannot grade it. So heads up to anyone else who has the idea of sending it in like I did lol
