1937-1959
1960-1982
1983-1994

In 1999-2000 the Canadian Mint announced the Millennium Coin Design Contest open to all citizen to submit a design with one to be released each month. The set from 1999 was meant to look back on Canada's past while the 2000 set was designed to look to the future.
2004 Remembrance Day coin
This was the first colored general circulation coin in the world.

In 2006, Canada released a Pink Ribbon coin in support of breast cancer awareness.
These 3 coins are the oldest ones in the set. The first one is too worn out to identify. The second one is a 1913 and the third one is from 1918
