A Raincoat Pikachu promo sold for $8.4 million

A PSA 10 Raincoat Pikachu promo just sold for $8.4 million with fees on Fanatics Collect.
That's the second most expensive Pokémon card ever, behind Logan Paul's $16.4 million Illustrator.
The same card sold for $19,200 in June 2025.
Only 100 were made and it was never sold in stores.

$19,200 to $8.4 million in about 15 months: real demand, or a few rich guys bidding each other up?
