These are rare and interesting vintage silver rounds from the Canadian Silver Marketing Co. They have a simple design bearing the markings "Canadian Silver Marketing Co, LTD 1974" on the reverse and "One Troy Ounce .999+ Pure Silver" on the obverse.
It appears this was an investment silver company from Victoria BC offering silver via newspaper ads between 1974 and 1975. You can see one such ad below from the "Daily Colonist" from August 30th 1974 a local paper on Vancouver Island.
These are well preserved pieces with almost no bag marks and markings on the coin surfaces, some pieces may have natural toning
