#1 First Basketball rules made by Dr. James Naismith

The first ever written basketball rules were the most expensive NBA or basketball memorabilia.
The first ever written basketball rules are the most expensive NBA or basketball memorabilia.

Dr. James Naismith, who invented the game of basketball back in 1892, also made 13 rules of basketball on January 11, 1892. Even after 126 years later, those rules are in great shape. These rules were auctioned in 2010 and were sold at a huge amount.

The rules book was sold for $4.3 million, that's pretty insane but what's interesting here is that these rules were then donated to the Kansas University for free. Another thing which is noticeable is this set of 13 rules was sold for more than some of the most important pieces of American history.

It's obvious that the invention of basketball changed the world of sports, but getting sold for $4.3 million is not easy for everyone to accept.
