Why the difference is price for signed vs autographed sports memorabilia?

Answer 1

Signed autographThere is no difference between signed memorabilia and autographed memorabilia. It is just deference in terminology. A signed Baseball is the same as an autographed baseball and the same value. An autograph is signed. You could sign a check or a document but the signature would not be considered an autograph. You sign a baseball or a photo and the signature is an autograph.
