Hi there,

Weight on these silver 25 cents is 5,83 gr with a tolerance of .04 gr. + or -
The same silver coins I have are within tolerance, except
these 2.
They weight 6.0 gr. I used 2 different scales and I come up with the same weight.

did you check your scale against a know weight?

acadien · February 17, 2020 8:49PM

Yes I have, using two different scales over and over and both still weight 6 gr

I also verified the CANADIAN COINS STRUCK ON PLANCHETS INTENDED FOR FOREIGN COINAGE no 64 and 65 quarters that weight 6.0 gr

Was the RCM striking coins for all of those countries at that time?

After verification None for that particular year. But I had to try, I have to search and see how did this happen.
