Skyrocketing Card Values Lately - Theories?

[MailboxBaseball]

Hello,

I am noticing some outrageously high card values/sales on eBay lately. This includes auctions as well as Buy It Now's.

It's not only Michael Jordan, but a few other key names in modern basketball as well.

Does anyone have any theories as to what is going on?

All I can come up with is that the government has been giving away lots of money over the last few months, and that people aren't spending money on vacations or at restaurants/malls these days til this all passes. Also, maybe that people are investing in the stock market less since it crashed in March.

The big question though is:

Will buying at these skyhigh prices be a mistake?
Once life returns to normal and people are all back to work, will the values of some Jordan cards and other refractors come back down to Earth?

Any insight or theories is greatly welcomed and appreciated.

Thanks
