A few friends and I were discussing what our favorite, or most random/unique, piece of sports memorabilia was, and I became curious to see what other people thought. My personal favorite that I own is a Ted Ginn, Jr-worn practice jersey signed by members of the 2003 team (including Troy Smith, AJ Hawk, Bobby Carpenter, Jim Tressel, etc). If I knew how to upload a pic, I would.

Your turn, what's your favorite?
