Surely, the buyer was confused. He probably thought he was buying a used 2011 Aston Martin for $50,000.00, which is about the right price, and not an 2021 Austin Martin card.
These modern collectors/investors are crazy. They are purchasing cards that are priced as if the player will win X number of championships, Y number of MVPs, and will finish their careers not only as hall of famers, but inter sanctum hall of famers at that.
I’ll stick to boring vintage. Cobb and Mantle aren’t having bad seasons, potentially sustaining season or career ending injuries, or being accused of sexually assaulting women.
