Does anyone know melt value of $1.00 Canda silver proofs?

[goodcents]

I've got 13 of these from the 1970's and all are 1 dollar silver proofs still in the case from the Royal Canadian mint.
I believe these are commemoratives. Most are 100 year anniversary of one thing or another each year.

I want to make sure I sell them at a fair price.

Thanks in advance.

Hi there,

According to my book, from 1971-1991 each round is .500 pure. They contain 11.66g or 0,38 troy oz of ag.

Cheers,
