There's been some press about Dmitri Young's PSA 10 rookie collection hitting the auction blocks. I read this in the
Yahoo! article:
"In the world of collecting, every collector has their own theme," says Joe Orlando, president of PSA. "If you are talking about baseball rookie cards in the highest quality, no other collection comes close to Dmitri's. The thing that's neat about his collection is that he's assembled not only Hall of Famers, but any noteworthy player in the post-World War II period."
...
"So when Horton's PSA 9 card popped up on eBay for $400, buying it was a no-brainer. Young sent it to PSA three times, asking that they bump it up to a 10. The third time they did."
How often do collectors resubmit a PSA 9 card 3 times and then get a bump to 10?
