In the 1936 Olympics, a tie resulted in the only time competitors walked away with half bronze, half silver medals.
In 1936, the Summer Olympics were held in Berlin, Germany. In the pole vault, a US vaulter named Earlier Meadows won the gold medal. The two who came in second and third were Shuhei Nishida and Sueo Oe, both of Japan. They hadn’t come explicitly in those places though. They had tied exactly. Japanese places, in the event of a tie, were often decided by a coin toss, thus Nishida was placed second and Oe third.
Japanese officials also had a hand in the decision, so many felt it was a little unfair to Oe. Nishida and Oe both weren’t very pleased with the outcome, so upon returning to Japan, Nishida and Oe decided to take their medals and split them in half. They then combined the halves to make two half bronze-half silver medals.
