I see 445 keys, you claim 475, I'm gonna need a screenshot chief

well 350 isn't indate anymore so it'd be 390 - 475, which has a median of 432.5 keys

Which is a 15% increase in value so I guess it would work, especially since lot of pure sales I guess

I also bought one for 475 recently https://imgur.com/qTp1okp

Compares for the other 475 mentioned in comments:
