We have what I believe is a 1952 Brooklyn Dodgers club ball signed by Jackie Robinson, Gil Hodges, Duke Snider, Joe Black, Pee Wee Reese among others. Can anyone tell me if these signatures are authentic or signed by the clubhouse guy? How can I determine the value and where would I even go to sell it? Thanks for any help someone could give. Hopefully the photos I have uploaded will post properly.
