    1980's 500 Home Run Club Signed Baseball. It's rare to see a genuine example of this signed ball, arguably the most forged piece in the baseball autograph market. An authentic example such as this should turn more than a few heads, as such are becoming more and more scarce in the collecting hobby. This ONL (Giamatti) ball features the entire gang of eleven: Mantle, Williams, Aaron, Mays, Robinson, Mathews, Schmidt, McCovey, Killebrew, Banks and Jackson. Each blue ink signature rates 9/10 or better. The ball shows a tinge of uneven toning, but nothing that can significantly impair the visual appeal, as our catalog imagery should illustrate. One couldn't imagine a piece such as this doing anything other than rise in value with each passing year, so smart investors take note. LOA from PSA/DNA. LOA from James Spence Authentication.
