  1. Can anyone tell me if they have tried weighing Canadian 1967 quarte's. As the mint changed from 80% to 50% silver midway through the year of 1967. I am having a hard time figuring this out I have read many times that there is no way to tell the 80% from the 50%, but the Canadian mist says there is a weight difference. Now I have heard of the water test but that is just not practical, plus I am just not that good at math LOL Any help would be very much appreciated Best Alan Technical specifications 1953 - 1967 Composition: 80%silver, 20% copper Weight (g): 5.83 Diameter (mm): 23.88 Thickness (mm): n/a 1967 - 1968 Composition: 50% silver, 50% copper Weight (g): 5.05 Diameter (mm): 23.88 Thickness (mm): n/a
