I was recently invited to participate in an appraisal fair at a local American Legion. One of the participants brought in a baseball with several HOF autographs, looking for an opinion. I advised that my subject matter expertise is limited, but offered to post here to try and get some opinions on value.

The father of the gentleman I spoke with was an acquaintance of a former MLB umpire. One of this umpire's claims to fame is that he was behind the plate calling Catfish Hunter's perfect game in 1968. In 1987, the gentleman's father asked his umpire friend if he could get a baseball signed by Mr. Hunter, who was being inducted into the Hall of Fame. When the baseball was returned, it not only had Hunter's autograph, but 13 others as well. The players who signed the ball (at the HOF dinner in 1987) are as follows:

Jim "Catfish" Hunter (HOF 1987)
Luke Appling (HOF 1964)
Lou Brock (HOF 1985)
Warren Spahn (HOF 1973)
Harmon Killebrew (HOF 1984)
Al Kaline (HOF 1980)
Billy Williams (HOF 1987)
Bobby Doerr (HOF 1986)
Bob Feller (HOF 1962)
Early Wynn (HOF 1972)
Enos Slaughter (HOF 1985)
Gaylord Perry (HOF 1991)
Brooks Robinson (HOF 1983)
Joe Dimaggio (HOF 1955)

The baseball itself is a Worth marked "NATIONAL OLD TIMERS CLASSIC".

I realize there are a lot of these group signed baseballs out there, and the value will depend on the signatories. The owner of the ball is not looking to sell, but was asking for an opinion of value. I told him I would post to this forum to attempt to get a better idea of value than I could provide on the spot at the event. Any help would be appreciated...Thanks!
