Thanks for sharing, its interesting to see Pokemon talked about on here. It's been a wild ride since about 2020. I've collected sealed Japanese since 2015 and have been astounded by its growth and strength. The new boxes I bought at retail in 2015/16/17 have at worse, 10x, and up to about 40-60x for the better ones. As well as benefitting like everything from covid/Logan Paul/crypto, it has continued this year for me. About 8 months ago I sold a couple boxes for £750 and £1350, I sold them again recently for £1800 and £1650, next time the number will start with a 2.
Whats the $102k card you mention? I can only think think of some trophy cards that are in that price bracket.
There were some bad choices as well during that time. The topsun charizard was a rollercoaster. The same card rode up to about $450k and fell back to about $100k.
