Here's a link to the Canadian penny law via an article written about it:
http://coincollectingenterprises.co...pper-pennies and
http://coincollectingenterprises.co...es-the-pennyIt states:
"No person shall, except in accordance with a licence granted by the Minister, melt down, break up or use otherwise than as currency any coin that is current and legal tender in Canada."For the silver... at least with nickels it shows:
(d) The prohibition contained in ยง82.1 against the exportation, melting, or treatment of 5-cent coins shall not apply to 5-cent coins inscribed with the years 1942, 1943, 1944, or 1945 that are composed of an alloy comprising copper, silver and manganese.Found that on

http://coincollectingenterprises.co...-legislationThat would suggest you can do whatever you want to the silver
War Nickels regardless of the laws pertaining to the nickel.
My understanding is fraudulent use of coins regarding the penny and nickel is primarily based on when you are taking a coin and using it for intent to extract value of it due to the metal value via melting/destruction.
Hope those links help! I browse the articles and links on that coincollectingenterprises.com site because they have a habit of always linking their sources of the facts they say.
