Agreeing with Pat on this... eBay is a good place to get the "value" of the card. However, it is a hit and miss when you are selling on eBay.
Case-in-point... a few years ago I picked up a Kyle Busch (NASCAR) autographed printing plate for a little under $10.00 because the guy had the name misspelled! It is Busch, NOT Bush. If he had spelled the name correctly he could have sold it for $100-plus.
My advice, if you are going to sell on the 'bay, make sure you do the following:
- Make sure you have at least ONE (1) good picture. Front and back is preferable for vintage and close up of the corners.
- Make sure you spell the players name correctly.
- Make sure you identify the card correctly (i.e., Topps, 1962, Mickey Mantle, card number, etc.)
- Older Vintage (I would say anything older that 1965) should be graded.
...and remember, just because one card sold for $150.00, that does not mean that your card will sell for the same price.
Good luck with your eBay sells!
