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
