Opinion of value of baseball- Ruth, Wilson etc

[theshleps]

I've owned this since 2010 and since I really do not collect signed balls have been thinking of selling. What do you think a fair value is? Description is as follows
This "Official League" ball (no manufacturer listed) features the black fountain pen signatures of fourteen members of the 1931 Chicago Cubs, plus that of Babe Ruth and Joe McCarthy. Ruth's signature (grading "8") shares the sweet spot with that of Cubs player/manager Rogers Hornsby (the signatures slightly overlap), while McCarthy's signature appears on a side panel. The remaining signatures on the ball are those of Hack Wilson, Gabby Hartnett, Kiki Cuyler, Charlie Grimm, Woody English, Riggs Stephenson, Billy Jurges, Guy Bush, Pat Malone, Bob Smith, Ed Baecht, Bud Teachout (on the ball label), and John Blake. There is one additional signature on the ball that is illegible. The signatures range from "5" to "8," averaging "6/7." While we can only guess at the circumstances of this ball's signing, it may have been obtained at a spring training game between the Yankees and Cubs. There is an area of light abrasion affecting the entire Teachout signature and a portion of the Smith signature. The ball has also been coated with a light layer of protective shellac. In Very Good to Excellent condition. LOA from James Spence/JSA
