Of all golfers of the last 75 years, one signed golf ball is unquestionably the most difficult to obtain - a signed ball of Tiger Woods. Obviously all Tiger Woods autographs are difficult to obtain, but signed golf balls are the most difficult, and most coveted, of all autographed items. In recent years, Tiger has simply refused to sign them.

This Titleist Stanford logo golf ball contains an early Tiger Woods autograph that dates to Tiger's college days between 1994 and 1996.
