Are any 50 cent coins made of pure silver?

Canadian 50 cents pieces 1911-1919 .925 silver 1920- 1967 .800 silver collector sets such as, butterfly, hockey legends, nature series etc all .925 silver you find if it is silver by using a magnet, magnets won't pick up a silver coin Silver is too soft to be pure, old silver coins are usually very worn, the copper is added to make it stronger and last longer. the new collector coins can be .925 silver, because they are in protective cases. If you have a new one, keep it in the case, older ones in great shape should be placed in a case asap. and never never never clean a silver coin, it takes away from the value or wears away some of the silver.
