This is definitely not my field of expertise, so if anyone out there is knowledgeable on this type of item I would be curious to know. A friend of mine has asked me if I could find out the ballpark value of an AL baseball signed by the 1949 Yankees. All the notables are there (DiMaggio, Berra, Henrich, Reynolds, Raschi, Berra, Bauer, Rizzuot, etc). The ball is in very nice shape. Any guesses?
