If you could do a buy out of any card and control the entire PSA 10 pop, which card would it be? Would you keep all of them/what would your starting price be? How would you distribute, if at all?
As for me, I’d buy out the Vs. Karen’s Umbreon with a market cap realistically around 16 million.
And remember any new PSA 10 adds would magically appear in your vault. 
I’d then list 50 of them at a million each to get the market moving, and release them only after 20 had sold. Then I’d start taking requests from anyone saying they’d like the card and generally why. Even if the why is to sell it and make money.
I think 20-50 million is a good amount to live off interest generally, and I’d probably then do a hundred card display I’d keep for my PC and controlling interest in the card. Then I could just spend my time playing Santa Claus with the rest of them. Fun
