I can answer most questions regarding the appraising, authenticating, buying or selling of modern (20th century to present) autographs of all genres including Hollywood, music, politics, sports and more.

I have owned and operated, the Web's #1 Place for Authentic Autographs, since 1999.

I am the world's top expert on Tiger Woods autographs, having followed his signing habits since 1996. I was featured on the premiere episode of the TLC show Auctioneer$ to evaluate a questionable Tiger Woods autographed golf ball.

Experience in the area

  • Active autograph collector since 1988.
  • Autograph dealer since 1997.
  • Owner, since 1999.
  • Former autograph columnist and feature writer for Beckett Publications.
  • Former Autographed Product Manager for Upper Deck Authenticated.
  • Baseball autographs, cards and collectibles columnist for Junior Baseball Magazine.

Something controversial or provocative about this subject

The companies that charge for third party authentication are not perfect. They make mistakes, both authenticating fake autographs and not authenticating real autographs. JSA is the most competent in my opinion and the only one you should consider. Avoid GAI, PSA/DNA and any others.

Samuel,    You can try but there is no guarantee he will reply. In fact I would say it's unlikely, but you don't have much to lose. Even if you get an autograph sent back, it may or may not be authentic

Trust me, a Dan Hampton autographed Sports Illustrated isn't worth anywhere near $2000. If someone actually paid that, they are stupid. Hampton's autograph is plentiful and not in high demand. I have Hampton

You'd send it to me. I will find out the discounted fee and let you know in case you want to submit it.    Are you trying to sell this card or are you just trying to verify the authenticity?    What is

2014-07-30 1986-87 Fleer Michael Jordan Autographed Card:
