The Royal Canadian Mint was founded January 2, 1908.
This medal shows the variations of the Canadian commemorative Dollars Minted (Silver Variations Pre 1968).
Included in these varieties are:
1935 - first silver dollar to commemorate the Silver Jubilee of King George V
1939 - Royal Visit
1949 - Newfoundland Entry Into Confederation
1958 - Founding of the British Columbia Colony
1964 - Confederation Meetings Commemorative
1967 - Canadian Centennial
It has no monetary value, but is a nice collector piece, especially if you have the commemoratives on the face.
