I found a 1999 canada penny that is magnetic. There is no P or RCM emblem below the queen on the obverse. Looks like every other Canadian cent of that year. I heard the steel composition pennies were supposed to be marked with a P for that year while the copper coated zinc were left with no mark. Do I have a rare one? -Bob |

Pictures, weight, and diameter please.
Inordinately fascinated by bits of metal with strange markings and figures

Weight is 2.27g. Magnetic. I cant find my caliper at the moment but it's the same diameter as a US Lincoln Cent of the same year. Maybe .01-.02" thicker. |

All my images are high resolution. Not sure how to scale them down on my phone to be under the 300kb mark.

To John1... I've been to that link. It's ot very helpful. They don't call out any coin compositions and they have disclaimers all over their pages about how the photos might not match the coin description. It's not very thorough. Checked alot of sites and all of them say that if it's magnetic (steel) then it should have a P below the queen.

If real your coin would be unique and quite valuable.
There were no 1999 steel cents struck for circulation.
The 1999p cents that were struck were samples for testing by the vending industry and some escapees have been found.
It is absolutely essential that you post clear pics of your coin.

From your pictures , your coin has the "mottled surface" that many zinc core coins have. If it is magnetic and a steel core then you would have an off metal strike and rare IMO.

 I'll say, that would be a super coin to find, but so highly unlikely. As said earlier, there are versions, but.....a serious fat chance in finding one in the wild. Can we ask for a pic with a magnet holding the coin with the date visible please. That would seal the deal, and I'm hoping you got one. Just touch the magnet to the edge and show us it's hanging.

Define "magnetic". There are certain materials like iron that exhibit a strong resting magnetic response due to the configuration of their electron spins.
However, you can induce a response in many metals and conductors by exposing them to a strong magnetic field. That is Faraday's law concerning induction. Waving a strong magnet over a wire, for example, will produce a voltage that moves electrons. Those moving electrons will produce an EM field with an E and M component. That M component will interact with the original powerful moving magnet.
One cool Alcoa attempt at recycling aluminum was to grind up all the trash and expose it to a powerful electromagnet. The field created eddy currents in the aluminum fragments, which had a magnetic component, which caused them to get sucked up by the electromagnet. Aluminum is not in the same magnetism class as iron (which is ferromagnetic), but it can still be magnetized by a changing magnetic field.
I believe if you wave a powerful magnet back and forth over a light zinc plate, you could probably get it to move. That doesn't make the coin magnetic, it just certifies that zinc is a conductor, which probably everyone already knew.
If the coin sticks to a static magnet and nothing is moving, then you've got something that's probably ferromagnetic.

Yes, I would also like to see the coin with date hanging off of a magnet.

The RCM minted 1 centisimo coins for Panama dated 1996 and 2001. It is 2.5g copper plated steel and appears to have a bit of a mottled surface. https://www.ebay.com/itm/145015753109It appears that Panama had no 1 centisimo coins dated 1997 to 2000. Maybe none were made then; maybe they kept using the 1996 die and some were made at the RCM mint in 1999. It is a possibility. This coin is off spec for a 1999 Canadian magnetic planchet (2.35g) regardless. |

I'm guessing we are not getting a picture of coin attached to magnet?
Guessing not a magnetic 1 cent
