I have been personally collecting baseball autographs for over 35 years and am beginning to sell off my collection. I think I have every player in the HOF since the early 1950s except Roberto Clemente. I have, in the entire collection, over 350 autographed baseballs. I also have several specialty All Star balls, World Series Balls, etc. All of my autographs have COA from either my company, nine9teen or the company I purchased the item from.
