Some more context, since it is MtG (not a sports set).
The one MtG card people might have heard of, if they've heard of any of them, is the Black Lotus. There was a version of it in three different sets, (Alpha, Beta, Unlimited). The most valuable one ever sold was an Alpha version [$166k] (pre-covid).
In the sets sold for these charities it includes the Beta version of the Black Lotus. While it doesn't go for nearly as much, one sold recently for $16k. And it was only graded 3.5. I don't know any sports cards from 1993 that would sell for that much being graded so low.
None of the cards sold in these sets were graded. The owner says they're all NM (in the video), and considering how serious he is about the cards it's hard to doubt that they aren't all in great shape. The buyer could probably have a couple dozen graded and make more than their money back. [A poorly titled article about expensive MtG cards: 7/10 are from sets sold for these charities]
I just think it adds a little more context for people who might not be as familiar with these cards. Yes, the guy gave away cards that sold for $140k. But they're really likely worth a lot more if/when graded. Think about it. He gave away enough to buy a house (most markets). He gave away some of the most valuable, most difficult to complete sets of MtG cards. In the video looking at his card room you can tell he's a huge fan of the game. And he gave them away. This isn't like just letting go of some spare doubles that are taking up space.
Pretty cool move.
