Thanks for the opinions, folks. I apologize for the photo quality- here's a cleaner version.
I agree with BillyCoxDodgers- the ball is toned, and it probably is a show-era specimen. I don't know if it is for sale or if the person who sent it to me is a potential buyer. It came to me from a friend who said something like "Hey...my buddy has this baseball, what do you think?" If he were asking for my opinion for his collection, I would suggest he get a better specimen, but since we are asking for donations for our Old Timers Banquet Auction, he may be thinking of donating it to us.
