Autographs

What Affects Value

  • The Player: HOFers, legends, current superstars command premiums
  • Item Signed: Premium items (jersey, bat, helmet) > photos > cards > index cards
  • Signature Quality: Bold, clean sigs worth more than faded or rushed
  • Inscription: "HOF 20XX" or stats can add 10-50% value
  • Authentication: PSA/DNA, JSA, Beckett BAS = required for serious sales
  • Deceased Players: Supply fixed forever, prices often rise

Authentication Companies

  • PSA/DNA: Most recognized, gold standard for autos
  • JSA (James Spence): Highly respected, strong for vintage
  • Beckett Authentication (BAS): Trusted, good for cards/photos
  • UpperDeck Authenticated (UDA): Direct from player signings

โš ๏ธ Forgery Alert: 50%+ of unauth'd autographs on the market are fake. NEVER buy expensive autographs without authentication. The $50 authentication fee protects a $500+ investment.

Game-Used & Game-Worn

Types of Game-Used Items

  • Game-Worn Jersey: Actually worn in a game - highest value
  • Team-Issued Jersey: Made for player but may not be worn - lower value
  • Game-Used Bat: Used in actual games - check for use marks
  • Game-Used Ball: From specific games/moments
  • Equipment: Gloves, cleats, helmets, pads

Provenance Matters

  • Team LOA: Letter of authenticity from the team
  • Photo Matching: Photos showing item in game use
  • MLB/NFL Hologram: League authentication programs
  • Player/Agent COA: Direct from source
  • Auction House Provenance: Heritage, Goldin, etc.

๐Ÿ’ก Photo Matching: Serious collectors use high-res game photos to match jersey details (stitching, stains, damage) to items. Photo-matched items can be worth 2-5x more.
