According to the Agence France Presse, medals from the Rio Olympic Games have begun to “flake apart”.
“We’re seeing problems with the covering on between six or seven percent of the medals and it seems to be to do with the difference in temperatures,” Mario Andrada Rio Games communications officer said on Friday.
The medals were made with recycled materials, and were given out to an estimated 2,021 competitors.
“Together with the IOC we’re setting up a system for replacing the defective medals,” Andrada said. “The medals will either be repaired or replaced.”
Prior to the 2016 Games, a total of 2,488 medals were produced. The gold medals were without mercury, and the silver and bronze were made from 30% recycled materials.
