Sell Your Cassius Clay Autograph
We sold the following Muhammad Ali/ Cassius Clay autograph items:
Scarce pair of boxing gloves, signed and used by Muhammad Ali (then Cassius Clay) to train for his second professional fight against Herb Siler in 1960. As an 18 year old, Clay signs and dates the left glove, ”From / Cassius Marcellus Clay / Dec. 19-60”, one week before he bested Siler in a TKO to advance his burgeoning boxing career. The long ink signature measures nearly 5” long and 1.5” tall and is unusual in that it includes his middle name, Marcellus. On the right glove is written in white, ”CASSIUS CLAY USED IN TRAINING HERB SILER 1960” and inside the cuff of both gloves is written ”C.C.” for identification purposes at the gym. These training gloves come with an LOA from noted Muhammad Ali collector Pete Morkovin who states that they were once part of the Columbia Street Gym Collection in Louisville, Kentucky. The gym was run by Joe Martin, the policeman who discovered Cassius Clay and introduced him to boxing after Clay had his bicycle stolen as a youth. Red leather boxing gloves by Spartan Sporting Goods Manufacturing Company include the original white laces. The gloves show heavy use, but remain in very good condition with no tears. Clay’s signature is strong, but lacks some contrast against the red leather. Among the earliest gloves attributed to Cassius Clay and scarce as signed. Sold for $15,000.
Muhammad Ali signed boxing bag glove, signed as Cassius Clay in the early 1960s after he won Gold at the 1960 Summer Olympics. He boldly signs the right-handed leather glove, ”From / Cassius Clay / World Olympic Boxing Champion / 1960”, well contrasted against the light tan leather. Glove is also signed by Ali’s brother, the boxer Rudy Clay. Goldsmith brand glove measures 9.25” x 5”. Some staining to leather and wear, consistent with use, overall very good condition. Lot also includes three photos of Ali, one from the 1960 Olympics and two of him boxing, wearing a similar glove. With a COA from boxing specialist Craig R. Hamilton. Sold for $12,500.
