There is some value to the ball, assuming it can be authenticated as used in the last NYY game from 1961. Autographed by Maris would be even better but, alas, that is now impossible. Please send me an email so we can discuss further.
There may be significant value depending solely on the provenance of this ball - in other words, the "who, what, when and where" of its history and how it was obtained. All information documenting the assertion its from Maris' record-breaking game would only enhance its value. Please drop me a line at stockyard2000@aol.com to discuss its value further.
