For PS1?

95% of games are below $60, and the vast majority of those are below $20.

You might mean “more than I’m willing to pay,” but it’s a market. There are millions of copies of certain titles, so no one is cornering the market. People are just willing to pay more than you. In the case of PS1, maybe $10-20 more. No one is getting rich from that.
