Question

How much more are graded baseball cards worth over non graded?

Answer 1

Seems like most graded cards of star rookies and star cards with pieces of memorabilia and autographs seem to command 10X to 25X the book values, if they are graded "pristine" or "gem mint" 10 by PSA or Beckett Grading Service.

I sold a UD SPX Star Rookie of Dwayne Wade, which includes an autograph, and was a limited print card on EBay for $9,500 as a "Pristine" 10 by BGS Grading.  In Beckett guides, the ungraded card was booking at $800-$850, so it looked like it was 10-15X the book value.

Answer 2

EDIT to Koala: Post the exact Ebay auction number and prove you sold that card for that price.

My guess is you wont post anything at all.

Answer 3

baseball cards cost $10 dollars to be graded so that raises the cost and mint condition cards are always worth more than cards in poor condition. If you would like to know how much more you could research or use the Beckett Baseball Card Guide.
