A friend of mine has these 5 Detroit team signed balls. 1 from 1946, 2 from 1948, and 2 from 1949. HOF's Greenberg, Newhouser, Kell and Lyons. She is looking to sell, and could use guidance on value. Not my space so looking for any help on estimated value. Unfortunately she is aleady into JSA for $150/ball, so looking to net something. Thanks for any help!
