and the second chart, obv it covers all card data without nuance for each era but the fact that it shows a version of @smpratte’s “K Shaped” recovery is fascinating. PSA 9s and 10s both saw a huge surge and then retraced, but held at a higher price than they started at - signaling that a general correction was in order. But, 10s retained more of that surge for longer.
you can also see something really cool in the Japanese vs English chart on your site
Japanese ASP actually overtook English during the retrace period. It would stand to reason that on average, a Japanese PSA 10 purchased in 2019 would fair best in 2022.
Obviously, there are more cuts you could do to get more specific insights but you don’t need me to tell you that (or ask for any more free analytics lol!). Thank you so much for your time already @TCGFish
