Graded cards
Verify the holder number and exact version; card grade and autograph grade are different.
Autograph cards
Distinguish manufacturer-certified autographs from cards signed later.
Championship memorabilia
A commemorative piece is not evidence of game use. Identify the Super Bowl and item type.
Signed jerseys
Compare licensed and custom display jerseys, size, signature placement and certification.
Signed footballs
Check the ball model and matching certification. A signed retail ball is not game-used.
Signed helmets
Match mini or full-size, replica or authentic construction, and display restrictions.
Signed photos
Check dimensions, hand-signed versus printed signature, framing and certification.
Kansas City keepsakes
Team branding does not establish player use, rarity or authenticity.

BEFORE YOU BUY
Look beyond the signature.
- Match photographs of the actual item to its certificate and the authenticator's database.
- Keep the claims separate: a real autograph does not prove licensing or game use.
- Check size and construction: mini or full-size helmet, custom or licensed jersey, printed or hand-signed photo.
- Compare the total cost, condition, seller terms and return policy before paying.
