magnetic coins

Hi

I have taken out a patent that relies on small coins being attracted to a magnet as per 1penny and 5 cent euro coin. A friend gave me some american cents and they are not magnetic. Can any one tell me if chineese or japaneese coins are attracted to a magnet? Are there any coins in us or canada that are attracted to a magnet.

Thanks

Yes, many US coins are attracted to a magnet.

 

Hi, can you be more specific as the coin needs to be very similar in diameter to a UK 1penny coin.

Canadian quarters and dimes are magnetic.

Really? Other than the 1,093,838,670 1943 cents, how many other US coins are magnetic?

 

Any coin that has a steel composition will be attracted to a magnet.Such coins include the obsolete 50 & 100 Lire coins from Italy,San Marino,
& the Vatican City.A coin that is struck from pure nickel,such as the Canadian 5 Cents prior to 1970 will also be attracted to a magnet.A cupro-nickel coin,such as the British 10p. coin will not be attracted to a magnet,as nickel & iron are elements,whereas,cupro-nickel is an alloy.Steel is an alloy,but its composition is mostly iron anyway.
Any of the small Euro coins (1,2,& 5 Euro-Cent) will be picked up by a magnet,as will the current British 1p. & 2p. coins.

 

There were some pure nickle 1930s 5 and 10 sen pieces, and some early '60s ¥50 coins.

 

Thanks for this. But so I am clear - are there no magnetic coins in common use in Japan today about the size of a 1 pence piece?

thanks

Thanks for this. Why do countries use different materials for low value coins? Am I correct that CURRENT Americian and Canadian coins are not magnetic in the 1P size?

 

Canadian 1¢ coins from 2003 and 2004 with a small P under the Queen's portrait are plated steel and are attracted to a magnet.

 

Except some 1998 UK 2 pences are bronze and are not attracted to a magnet.

 

sounds like your doing some counting machine or something

most of they work by the electric resistance to determine there legal in coin slots

 

thats also a sure fire way to find fake coins.its how the modern gold testers tell the karat of gold too.

if you have a morgan dollar and a fake one just check the resistance and you can find out that it is a fake.

unless the fake has been made to exact composition to the original its easy to tell what it is.

 

Current Japanese circulation coins are aluminum, brass, bronze, cu-ni, or ni-brass. Commemoratives are silver or- gold.

In other words there are currently no magnetic Japanese coins of any size.

 

No, they are not. Get a magnet. Get a coin. Do any U.S. coins stick to a magnet? "Steelies" (1943 cents) do. No other American coin will.

However, it is true that modern American coins are "magnetic." Placing a 5-cent nickel in the field of the magnet will distort the field. A piece of paper will not. Nickel is "para-magnetic" -- it has magnetic properties but it is not "strongly" magnetic.

 

Your chauvanism is showing Mike!

It's true that a magnet will not attract any U.S. coins except a '43 wheatie, but when was Honduras expelled from the Americas?

I haven't scoured Krause for other examples, but if my 1994 50 centavos FAO from that Central American country wouldn't stick to a magnet, it would indeed be a very strange piece of nickle-plated steel.

What is your basis for believing that the citizens of more than a dozen countries in North, Central and South America are not "Americans"?

 

Not all steels are magnetic either. There are various stainless steel alloys that are non magnetic.

I don't know what kind of patent you are hoping to get but I don't think it's going to be of much value, if they even grant one.

 

In short as far as buisness strike, circulating coins..All new canadian coins ARE magnetic and all new U.S. coins are NOT

 

There are some 2003 & 2004 1¢ CDN coins that are not plated steel and are not attracted to a magnet.

 

All Canadian 5c from 2003 on are magnetic, and simular in diameter to the 1p.
