Coins made of mostly nickel, or containing steel, will be attracted to a magnet.
Canadian nickels, dimes, and quarters made in the late 20th century were made of mostly nickel, which was comparatively cheap in Canada. Conversely, from 1982 to 1999, Canadian nickels were not magnetic, being mostly copper like US nickels. Beginning in 2000, all fractional Canadian Coins have steel centers, and are magnetic. $1 and $2 coins are not magnetic.
You can exchange Canadian pennies for US currency at some banks or currency exchange locations. Alternatively, you can keep them as souvenirs or donate them to charity.
No, 1944 pennies do not stick to a magnet because they are primarily made of copper, which is not magnetic. However, during World War II, some pennies were made of zinc-coated steel, specifically in 1943, which would be magnetic. If you have a 1944 penny, it should not be attracted to a magnet.
because i ate some of them
All U.S. cents issued since 1982 have been struck in copper-plated zinc which is not magnetic. If you have a magnetic U.S. cent with that date it is either a fake or an altered coin. Since 1992, U.K. pennies have been struck in both bronze and copper-plated steel. However, all 1996 coins were struck in steel so they will all stick to a magnet. If you have additional information, please post a new question.
All of them are collectible, some are worth more than others.
yes; if you look closely it is very easy to tell
Do you mean numismatic value or monetary value? For numismatic value it would depend on a wide range of things (the year of the coin, the condition, etc). Some Canadian pennies are worth a cent or two, while others can be worth hundreds (even thousands!).
1943 silver pennies
The property of magnetism made it possible to separate the mixture with a magnet. Some components of the mixture may be attracted to the magnet while others are not, allowing for separation based on magnetic properties.
Among American pennies (cents, actually) only the famous wartime steel cents made in 1943 are magnetic. All other US cents are made of metals such as bronze or zinc that aren't attracted to a magnet. In 200 Canada changed the composition of its cents to copper-plated steel, so those coins are attracted to a magnet but earlier issues aren't British pennies have been issued in both bronze and copper-plated steel so depending on the year of issue they may or may not be attracted. In some years both compositions were used, which makes things a bit more confusing. Euro cents are all made of copper-plated steel so they too are attracted.
catsup is American and ketchup(the correct spelling) is Canadian
No, the mongoose is a mammal that some people use to ward off cobras. The Canadian goose is a bird that migrates with others of its kind in a "V" formation.
