I thought this would be a good way to get some additional information out there to the members on the "worth" of their cards. ALL Members, please feel free to post your comments and suggestions to this thread to help out our fellow collectors (new and old!) To start off this thread I thought I would give you some examples of "Book Value" versus "Sale Value". (Sorry, using NASCAR as an example) Robbie Gordon 1997 Jurassic Park Thunder Lizard TL10 - High BV $15, but try to pick one up at a Card Show and expect to pay $20-plus for it. Currently there is one on eBay with a "Buy It Now" price of $20. A Mike Skinner TL9, from the same Thunder Lizard set, has a BV of $5, but try to pick one up for under $15-$20. Now, at the other end of the spectrum we have Dale Earnhardt Jr. His 2011 Legends Prominent Pieces (Firesuit, Sheet Metal, Tire) #/99 has a BV of $50, but you can pick these up at Card Shows for around $10-$15. On eBay you it will run about the same (including the shipping). When it comes to Book Values... it's user beware. You have to ask yourself "Do I really want/need that card for my PC?" When I put the 1997 Thunder Lizard set together (many years ago), the Robbie Gordon had a BV of $5. I laid out $25 for it, because I NEEDED that card to complete the set. Enjoy the hobby... and don't worry too much about BV versus SV... that is, unless the person you are trading with decides that your $100 autograph is equal to his $10 worth of base cards.
