Brazil's Central Bank issued a large series of bimetallic circulating commemoratives for the Rio 2016 Games — one coin per sport — making this among the most ambitious Olympic coin programs ever produced for everyday circulation rather than collector sets. The sailing events were held at Guanabara Bay, a venue that drew considerable controversy in the lead-up to the Games due to severe water pollution and concerns about athlete safety.
