When I was a kid, I bought a heavy Spaulding baseball bat at a garage sale near my house. I still have the bat today; it’s endorsed by George Grantham, who played for the Cubs, Giants and Reds through the 1920s.
I looked everywhere online, and couldn’t find any references to any Grantham-endorsed bats. I’m wondering where, aside from eBay or a mom-and-pop sports memorabilia store, I can find out more about this bat, and maybe get it appraised and sold. Any thoughts?
