Magnetic 1945 D Wa Nickel

see how much it wieghs

Possibly was buffed to an unnatural shine.

put it in some acetone to get rid of the tape residue.

get the weight to make sure it is real.

Thanks for all the replies. I just found them all in my spam folder - I will have to fix that.

"Is that tape or discoloration. ?" - it is some sort of tape or glue residue on the back


"The powerful magnetic field from a rare earth magnet is enough to attract the manganese in the alloy." - I have 3 other War Nickels and the same magnet does not attract to the at all

"see how much it wieghs" - It weighs 5.1 grams and my 3 other War Nickels weigh 4.9 gr, 5.0 g and 5.0 g

"put it in some acetone to get rid of the tape residue." I did not want to clean it until I fould out more about it.

Conder101 is correct


Manganese at 9% is lightly magnetic in the wartime alloy.
A single neodymium magnet is usually not powerful enough to pick 1 up. So your test with other nickles is the norm. I suspect that the alloy mix the Mint used that day was off. or your other coins are hennings!

We use a manganese, silver, copper, (war nickle) test for power of completed arrays.
In comparing magnets a 15# pound pick up retriever neo. does not have the strength to pick one up, but can move it around.
Our least powerful array, at a minimum has to be able to pick up and hold one.

Many off metal counterfeits have ferromagnetic properties
that we have to screen out before testing in our inductive signature scanner.

If you want to sell the high magnetic nickle I would be interested, as an error coin!

edit for

sounds logical but
Cupronickel 75% copper 25% nickel is not attracted to the very powerful magnets we use.

However pure nickel bullion and coins are.

Can anyone tell me exactly why?

Pure nickel is actually very STRONGLY magnetic. But in an alloy it usually loses most of its magnetic properties once the percentage of the other metal exceeds about 10%.
