I have been asked to get feed back on this item. 1959 cent silver in colour and weighs 3.3 grams and is magnetic. I appreciate any information.     |

back then they were made of copper and that isn't magnetic so a penny shouldn't be magnetic.. maybe an off-metal strike? But the rim and edge look as if someone played around with the coin. Hopefully someone with more experience in errors can help out shortly!

could easily have been someone's trial for nickel plating?

is it slightly magnetic, or full on magnetic like a steel and or nickel coin. The copper core nickels of the 90's are nickel plated and even with a neo=mag they don't seem to hold one in the air.

It's strong to a magnet, holds more than its own weight in the air

3.3 g is too light for a nickel planchet (should be 4.5g) it could be some sort of foreign planchet. It would need to be XRF'd to see what the metal content was.

It's definitely a magnetic core then, off metal planchet, that would fit nicely into my birth year error set, lol. Xrf is the way to go as mentioned previously.

...off metal planchet, In 1959, that is unlikely. The RCM did not strike coins for other countries in the late 1950s. However, Canadian 5c nickel planchets were sometimes sourced from the Sherritt Mint in Edmonton. The Sherritt Mint supplied planchets all over the world. So maybe one of their planchets got mixed in with a Canadian order... maybe... Note also, nickel plated coins can become quite magnetic, if enough nickel is used. Given the full collar, full strike, and the weight (normal 1c coins are 3.24 grams) - I tend to think that is what we are seeing.

SPP, I can't see how this said coin could support more than it's own weight on a magnet with only plating. I've never seen that before. Do you have or have seen an example of such? I'm only basing this on %age of metals in the coin to act in such a way.

I dunno, a friend posted this for me and it's the coin I have had questions about and was thinking of having it graded and wondered if that would tell me anything. What goes into the process of grading does anyone know? Will it tell me what it is? I got it through change and was passed off as a dime

There is a blob above the Queen's head, it just looks plated

Grading won't tell you what it is as I don't believe they use an xrf for the varient's of metals in the coin. SPP has access to an xrf and can break down the %age of metals to the decimal point. He has done some xrf'ing for me in the past and I was totally impressed with the results, scientifically based of course. You may be able to get this figured out through this avenue.

Yes - it really depends on the magnet. If you have one of those ultra strong rare earth magnets from Lee Valley, you can lift up almost any nickel-plated coin. Of course, I am happy to put it on the XRF I have in my lab - you only have to pay the postage.
