Summer Olympic Coins (2000–present)
Traditionally, Olympic coins are numismatic coins. However, several host countries minted so many coins – particularly silver ones – that their value has become just slightly above the value of their metal content. Coins for the 1976 Montreal, 1984 Los Angeles, and 1988 Seoul are generally considered to fall into that category.
There have been cases, though, in which host countries minted circulating commemorative coins. For example, Canada's Lucky Loonie program and its 2007 25-cent pieces to commemorate the 2010 Vancouver Olympic Games, and Brazil's 1-real pieces that commemorate the 2014 Rio de Janeiro Olympic Games.
