The “Big O” Oscar Robertson recently had one of his NBA memorabilia auctioned off for a staggering amount. As discussed by Alec Nathan of Bleacher Report, Robertson's one and only championship ring from the 1970-71 season has been sold for an astounding price of $75,948.

This piece of history was auctioned off on sports auction website Lelands.com along with several other items as part of The Oscar Robertson Collection.

Interestingly enough, Robertson's championship season was actually not his most impressive year as a pro, statistically speaking.

After being drafted first overall by the Cicinnati Royals in 1960, the 22-year-old immediately paid dividends to his club. Robertson went absolutely nuts right off the bat and was deservedly awarded the Rookie of the Year title in his debut season. The year after, the 6-foot-5 point guard made history by being the first player to ever average a triple-double in a season with an output of 30.8 points, 12.5 rebounds, and 11.4 assists.

As we all know, this feat was replicated more than half a century later when Russell Westbrook averaged 31.6 points, 10.7 rebounds, and 10.4 assists in the 2016-17 season. To this date, they are the only two players who have accomplished this amazing feat in the entire history of the league.

At $75k, a lot of money was spent on Robertson's ring. However, it does not come close to the most expensive piece of basketball memorabilia. According to Sportskeeda.com, this honor belongs to the original copy of the rules of the sport penned by Dr. James Naismith himself. It was purchased for $4.3 million back in 2010.
