[Misunderestimated]

The highest end of the market for basketball (NBA & WNBA) is largely about (manufactured) scarcity and potential. Didn't some Luka Doncic one of one card set the basketball card price record a few years ago ? He's really good and the sky was the limit on his potential (it still may be).
Clark is like that --> only more so. She's got potential to be the one of the best ever and has elevated women's basketball's popularity like no one before.

I guess the difference between her cards and the Mantle card referenced below is the potential both upside and downside depending on how her career shakes out.
One of the things I find most interesting about her celebration/phenomenon is that she plays for Indiana a basketball heaven but not exactly a large market. I guess that doesn't matter like it used to.
