Canadian 1967 silver quarter's ???

#1 Unread post by acan451 » Sun Apr 05, 2020 2:08 pm

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

It is actually caked the Specific gravity test
Weigh coin on your scale, then.
Place each coin on a string so it does not touch the sides or bottom in the water, then place the container on the scale
Then take the weigh again then do the math ? and there you go.

This is what I have read but don't know anyone who has done it
