When I do searches on eBay that involve jersey cards, I usually end up getting cards that manufactured. They aren't cards that you get from Upper Deck or Topps.
Here's a Derek Jeter jersey cardI don't understand.
National Sportscard Authenticators created the card, included a game-used jersey, threw it in slab and viola.
Is there a market for these cards? Because at the price they are charging, I can two, maybe even three Jeter jersey cards from Topps or Upper Deck. Then again, these days how do we even know those are real?
