1976 Montreal Summer Games 

Most numismatists agree that the first true numismatic collection was the Olympic Five and Ten Dollar coins for the 1976 Montreal Olympics. Starting in February 1973, the Royal Canadian Mint (RCM) engaged in a very ambitious program. At the behest of the federal government, led by then-Prime Minister Pierre Elliott Trudeau, it was agreed that these coins would help finance and commemorate the 1976 Summer Olympics. 

The plan was to have thirty coins, twenty-eight silver coins with face values of $5 and $10, and two gold coins. This would signify the first time that the RCM issued coins with face values of $5 and $10. These coins would be categorized into seven series with each series configured into four coin sets (two five dollar coins and two ten dollar coins). The seven series were constituted as follows: 

Geographic 
Olympic Motifs 
Early Canadian Sports 
Olympic Track and Field Sports 
Olympic Water Sports 
Olympic Team and Body Contact Sports 
Olympic Souvenirs 

The $10 denomination coins have a gross weight of 48.600 grams while the $5 denomination coins have a gross weight of 24.300 grams. Each coin is 92.5% silver for a net silver weight of 44.955 grams (1.4453 troy ounces) and 22.478 grams (0.7227 troy ounces) of silver respectively. 28-coin set consists of (14) $5.00 and (14) $10 coins. Each coin of this set comes to you in an individual capsule housed in a handsome collector's case. Certificate is not included.
