How Many Grams Does a Canadian Loonie Weigh?

The Canadian $1 coin, commonly called a “loonie” due to the loon pictured on the back, weighs between 0.24 ounces and 0.82 ounces. The exact weight depends on the issuing year of the coin; older coins are heavier.

Loonies minted between 1935 and 1967 weigh 23.3 grams, those minted between 1968 and 1986 weigh 15.62 grams, and those minted between 1987 and 2012 weigh 7 grams. Newer loonies minted between 2013 and 2014 are the lightest, weighing 6.27 grams. The variances in weight are due to changes in the metallic composition of the coins between minting runs; the 23.3-gram 1935 loonie is 80 percent silver and 20 percent copper, while the 6.27-gram 2014 loonie is multi-ply brass-plated steel.
