I have been selling some of collecting of cards and coins on eBay and thought I would share some inside on how to buy. 
This 1986 Steve Young rookie card sold for $330.00 because it is a PSA graded card.

There is no difference in the grad of these cards the only difference is the company that graded the cards. 
Lesson Don't Pay $317.00 more for something that will sell for just $13.00.
