The Naismith Memorial Basketball Hall of Fame ring presented to the legendary Elvin Hayes at his induction in 1990 has sold for $56,250.
The lot provided the highlight of Nate D Sanders' online sale, which closed on May 29.
The Washington Bullets star is regarded as one of the greatest players ever to step on to the court, with his impressive scoring average of 21 points game ranking him in the NBA top 50.
The ring is cast from 10k gold and engraved with images of basketball players, while the head features a diamond set on a red stone.
The Hall of Fame trophy presented to Bernard King, another player of huge significance, made $40,625.
King, who made the all-star list four times, was inaugurated in 2013 after retiring from the game in 1993. During his career he played for a number of teams, including the New Jersey Nets, the Washington Bullets and the New York Knicks.
It was during the 1984-1985 seasons that he achieved his career high, when he set a scoring average of 32.9 - making him the top player that year.
The sale included a number of rare space memorabilia items, including an Apollo 17 Robbins medal owned by astronaut Jack Swigert.
