Kevin Garnett topps rookie card boom

[ljandkg]

I know things are taking off AGAIN in the hobby, and it's crazy to watch, but it's worth mentioning individually the rise of KG's topps rc card and why it's taken off.
I don't have time to see who is influencing what in the trading card scene. I'm wise enough to know that people with a bit of influence/tonne of followers online can change prices dramatically.

This week KG's Topps rc PSA10 officially had a sale for $2500. There's been numerous sales in the preceeding week for $2000 plus. Two years ago this same card PSA 10 sold for $15-20.

A year ago when Covid hit and the first boom in the hobby hit, it went up into the $400-500 bracket.

I showed a work colleague some of this the other day and I couldn't explain why it's happened other than I'd heard someone like Gary V had said another boom was coming. Also being overseas and far removed from what's happening with investing etc in the US I wasn't able to explain why it'd happened very well.
Is it as simple as investors with cash are buying up cards instead of investing elsewhere because of the quick returns?
Can anyone spell it out for me a bit better?
Firstly for the whole hobby spike again, and specifically for this topps rc card for KG ahead of any of his other 14 rookie cards?


Disclaimer - I have my one topps rc card at PSA and boy do I hope it comes back a ten before this all deflates!
