We created the Uncommon report to celebrate the All-Star personalities whose legacies resonate both on and off the field, and drive sales as a result.”

Beyond The Uncommon

Uncommon cards can be just as valuable and noteworthy as the players they represent. Specifically, error cards have a certain nostalgia that sports card collector’s love; many of these types of cards are talked about daily in the hobby and can only be found on eBay. Throughout card history, notable printing errors on cards have occurred and while some would argue these mistakes are sometimes intentional, others would say these lead to future “rarer error cards,” because a correction card had to be made. Whether these cards were eventually corrected and replaced or left unchanged, there is a chase element on many error cards, because they are so rare and valuable.

The 5 most sought-after error cards on eBay (2010-2020): 

  1. 1989 Billy Ripken FF Card

  2. 1990 Frank Thomas No Name on Front Card

  3. 1969 Mickey Mantle White Letter Card

  4. 1989 Upper Deck Dale Murphy Reverse Negative Card

  5. 1981 Fleer Craig “Graig” Nettles 

Most recently - crossing over into pop culture - a misprinted 2019 Shane Bieber, pitcher for the Cleveland Indians, card was mislabeled as Justin Bieber. In response, searches for Shane Bieber spiked more than 500% when the real @JustinBieber called out the error on Twitter.

All of these player stories, and the collectors who make it their mission to source their cards, are of course set against the backdrop of this truly uncommon 2020 MLB season. Stay tuned for more details on Uncommon and unique trading cards on eBay. Shop and explore eBay’s Uncommon Report at
