You don't. That is against the law. It is a violation of both the Currency Act and The Canadian Criminal Code to deface or destroy a Canadian coin.
The law states: ''no person shall melt down, break up or use otherwise than as currency any coin that is legal tender in Canada.''
By the way, if you mutilate the coins, they cannot be used any longer. The Mint won't take damaged coins. They will with bills, but not coins.
In US dollars it has a melt value of $1.37. It is illegal to melt these coins for the metal they contain.
No it's not illegal to do this.
YES
Yes, it is legal to melt down silver coins for scrap. Many coin dealers and jewelry stores will buy them from you at melt prices along with refiners. The only coins illegal currently to melt down in the US are pennies and nickels. Silver coins were illegal to melt down before a lot of copper-nickel coinage was circulating but it is legal now.
None.
I deal typically with melt value, your coin is worth about $1.81 melt value with 80% silver. However, you may want to check this coin on Ebay coins to see if it is worth more as a collectible.
No. Canadian 5¢ coins haven't contained any silver since 1921.
In US dollars it has a melt value of $1.37. It is illegal to melt these coins for the metal they contain.
The melting point of silver is 961.8 degrees Celsius (1763.2 degrees Fahrenheit). Silver coins would begin to melt at or close to this temperature, depending on the purity of the silver and any other alloying metals present.
Last year for Canadian silver content coins was a partial production in 1968. A magnet will pick up newer quarters but not pre 1968 silver coins this includes dimes as well.
1920-1966 Canadian coins have the following value as of March 2 with SIlver prices at $34.69 per ounce. Dollar: $20.81, Half $10.40, Quarter $5.20 Dime: $2.08. These are all $80% silver. In 1967 and 1968 Most Canada coins went to 50% silver. After 1968, there is no silver content. This answer is from a silver perspective only. There are rare and collectible coins that have no silver.
No. find the website for Calgary Coins. There they will tell you the metal content and a VERY brief history of Canadian coins. 1968 was the last year silver coins were minted for circulation, and then only for part of the year and in debased .500 fine alloy.
