Over 100 Rio Olympic medals are defective

The Rio Olympics has its share of problems going into last year's games -- and months after the festivities concluded, there is still an outstanding issue.

Reuters reports that over 100 medals have been returned to organizers due to defects. Out of the over 2,000 medals handed out at the games, Rio Games communications officer Mario Andrada told AFP that around six or seven percent may have problems.

There seem to be two flaws with the medals, mostly bronze and some from the Paralympics: the main problem is tarnishing and rusting, and a small number cannot handle the extreme cold.

Andrada said the Brazilian Mint will fix and return the medals in question. The silver and bronze medals were made with 30 percent recycled materials.
