I think a lot, but not all of it - is pandemic boredom and some FOMO creeping in when people look at what Ruth, Cobb, and other popular prewar cards have done in the past two years or so. The postwar HOF key cards and marquee rookies are in the same boat.

I would not expect the bubble to last forever, but some cards will probably not dramatically lose steam even if it doesn't. I don't think multiple rounds of government checks and sports gamblers having to stay home for so long have helped us at all in the past year, however.
