Or maybe we who buy and sell these items obsessively stop judging what others do? How am I going to tell some kid not to sell a Wemby jersey that might net him a college tuition?
This all reflects who we are as a society and as a subculture of collectors. The idealized innocent experience of meeting a hero and getting a valueless autograph as a memento is a fantasy that hasn't really existed for decades (except maybe in children's cancer wards), ever since the card collecting and memorabilia boom began in earnest. We are to blame, of course, for creating, enjoying, profiting from, and evangelizing collecting. It's capitalism, baby: we cannot expect to create a huge market for these items and then tut-tut anyone else for figuring out how to cash in using methods we never even considered. I'm just sorry I didn't get the idea first.
But I digress...
I don't see the appeal, except financial, of getting a Koufax auto at those prices. Now, that said, I could see getting a rare or significant card signed, like this one:
Card is tough as hell; can't think there are too many signed ones.
