From the 1940s listed in Hake's Pop Culture Guide as rare w/less than 10 known. In addition to its rarity, this example is in high grade. It grades NM w/mere traces of wear under magnification but o/w displays Mint w/glossy, probably nickel-plated, silver luster. The solid band is like an arm w/a boxing glove on each end that bears "Joe Louis" signature on each glove and flanks the realistic, finely-detailed, high relief portrait of him. Ring is an adult size 8.5. Rarely offered and we've seen only one other in equal condition in our 47 years. The Hake Pop Culture Guide NM value is $3,750. See Joe Louis Ring sign, #942.
