It will all depend on the brand (Panini and Donruss in baseball worth less because they don't have the rights to use the logos). Most cards are down at least a little since February, with a few outliers of course. I think it had to do a little with market correction and a little to do with the pandemic coming to an end and people using their money for other things than their hobbies now.
Nice to have that Giannis rookie though, wish I had one ;) I do have the Tatis though, nice card to have.
