For graded cards, TCGFish, Fanatics Collect, Goldin, and Heritage historical auctions / BINs. PSA’s website does track some older sales as well from the mid 2010s.
For cards that aren’t graded, there isn’t a website to my knowledge. Mavin.io used to go back many years, but the company shut down. TCGPlayer only goes back a year and it’s unhelpful for most vintage cards. 130point will not go back very far. Terapeak will go back 3 years, but it doesn’t pick up everything due to keywords.
There are some threads on e4 where people discussed specific purchases from a while back or “best purchases” over the years. I wish we had something as comprehensive as what you are looking for.
