Three Everlast manufactured single leather boxing gloves single-signed by Mike Tyson and Floyd Mayweather Jr. Tyson signed the two right-handed gloves in black and silver marker with one illegible inscription in black and Mayweather signed the left-handed glove in black marker and in our opinion the signatures rate a combined 8. Both Tyson gloves have a PSA/DNA sticker and the Mayweather glove has a JSA sticker. Accompanied by a LOA from JSA.
