Rare 1930's Cartier 9K Gold Boxing Medal Brooches – Amateur Boxing Association

A Rare Pair of 9K Gold Medals Honoring R.A. Cosgrove’s 1935–1936 Boxing Triumphs

A remarkable pair of 9K gold boxing medals, retailed by Cartier in 1936, commemorating victories in the Amateur Boxing Association’s Schoolboys Championships. These exceptional medals were awarded to R.A. Cosgrove, the 1935 Intermediate and 1936 Senior Champion — an extraordinary back-to-back achievement in British amateur boxing.

Each medal is richly engraved on one side with the figure of a boxer or two opponents in the ring, surrounded by laurel wreaths and the inscription “Amateur Boxing Association.” The reverse sides are finely inscribed with the competition details:

• 1935 Intermediate, 7 st. 7 lbs – Winner R.A. Cosgrove

• 1936 Senior, 8 st. 7 lbs – Winner R.A. Cosgrove

Crafted in solid 9K gold and joined by a delicate gold chain, the medals bear clear Cartier retailer marks and British hallmarks, confirming their authenticity and quality. Their conversion into brooches — complete with period fittings — transforms these historic awards into elegant wearable trophies, preserving both their sporting and artisanal significance.

During the 1930s, Cartier London frequently collaborated with prestigious sporting associations, supplying presentation pieces and custom commissions for elite events. These brooches exemplify Cartier’s rare intersection of luxury design and athletic heritage, embodying both strength and refinement.

This pair stands as a tangible link to the golden era of British boxing — a time when discipline, artistry, and excellence converged. A true collector’s piece, it represents a unique fusion of sports history, craftsmanship, and Cartier’s enduring legacy.
