Even if someone did, I'd be super curious as to the actual return. The highest priced card sold at auction for a "you could just find it in a random pack of Pokemon cards" I could find was around $20k; all the higher priced ones were either due to printing errors (so -extremely- limited runs that you were unlikely to actually get ahold of just buying cards), or were special runs for special events (so also not something you could just buy).
Given that, the decades now that Pokemon cards have been sold, the implications buy in would have (i.e., if you went all in on Pokemon cards as soon as they hit the market, you presumably are going all in on every big IP CCG as a potential investment path, or just as liable to pick losers as winners. Those Star Trek CCG cards haven't exactly held their worth), I'm pretty sure you're not coming out ahead even if you did.
