Hi, yes it sticks to a magnet and feels by hand to be same weight as a normal dime, I don't currently have a scale to accurately weigh something this light but I will get a scale, weigh it and get back to you.

A regular modern Canadian 10 cent coin has 3 coatings on steel: Nickel, copper, and then nickel again.

I have handled a number of 10 cent errors, it could be a plating error or even a foreign planchet strike, or, a post mint alteration. These are tougher, because most foreign planchet barely fit the collar and are usually fully struck. I can't say much more unless I see the coin in hand.
Is the thickness and weight similar to a similar 10c of the same year?

@darryldarryl - Your theory sounds very plausible!
@SPP-Ottawa - Do you know what would be most rare out of a plating error, a foreign planchet strike, or a post mint alteration?
I am getting a scale tomorrow, will weigh it against a 10 cent dime from same year and post my results here.
Thanks for the info!

UPDATE: I weighed the 2019 copper looking dime against a regular 2019 dime using a professional digital scale and they both weighed exactly 1.75grams The copper looking coin also has the same milled edge as the regular 2019 coin as you can see in the attached image.  |

Take a drive to Canadian Coin and Currency, ask them to XRF it, because of the date it could be worth a couple hundred bucks if not PMD. The XRF will tell if it's a foreign planchet, missing plating or PMD |

@john100 - Do you by any chance know if Canadian Coin and Currency will XRF the coin for free or what the cost is?

Pretend you want to sell it and you need an XRF to find out what this coin is, almost sure they will not charge you, people bring in silver items to sell and they XRF to find the scrap bullion value

justins - ask for Alfredo when you get to Canadian Coins & Currency, and tell him that "an error guy in Ottawa" told you to go there, and get it tested. They know me well as an error person, and I have helped them out a bit with errors recently. They should not charge you - it is a test that takes only a minute or so.
Now, with the XRF, bear in mind that it is a penetrative study by an iridium beam source, so you will still get a strong Fe result (the steel core, and why it is magnetic), you should get a weak Ni result (these coins are multi-ply plated with Ni, then Cu and then Ni), and you'll get a strong Cu result (being the surface layer). Depending on the power of the XRF, the results may be inconclusive. You have a better chance of making an appointment with Steven Bromberg at CC&C and ask him to examine the coin directly. Most folks don't know this, but Steven really knows his errors as a coin dealer, probably better than most. He might be able to tell you pretty quickly if it is legit (by the strike and lustre) or a coin that was plated after the strike.

@SPP-Ottawa - thanks for all of this information and contacts. I will try to make an appointment with Steven, as he seems like he could be my best bet right now into solving this mystery. Thanks again to you and everyone else who has taken their time to respond to my post, what a great community this is!
Will post any future updates/findings here.
