What is the weight? Is it attracted to a magnet?

I don't have a scale but yes it's magnetic. But so is the regular bronze plated.

DaisyDuck:  to the CCF !I am guessing that it may be thin nickel electroplated, perhaps in a high school lab experiment. Color looks the same as the 25 Cents. |

Ya it is! I think all loonies are some sort or nickel based and bronze plated so is this one a miss print and didn't get played? I've never seen one and can't seem to find any info.

To CCF! It's probably been plated. Not an error if it is plated. Errers and Varietys.

It could have been made on a planchet meant for another denomination or a foreign coin. That's why the weight was requested and is important.
Loonies aren't plated; They're made of an alloy called aureate which is a solid colour all the way through. If the "nickel"-coloured coin was plated, I would expect to see some of the under-colour showing through in the worn areas.
If the weight turns out to be the same as a loonie, then it's probably a plated coin (and I was wrong above). The way to tell is to make a small scrape on the edge and see if the normal loonie colour is under.

Do not damage the coin, first go to a Canada Post outlet ask nicely their scales are really accurate and if needed an XRF will tell the story, I have one in a PCGS holder believe it says loonie on an unplated planchet

I have a no aureate plating loon I won at auction back in 2012. ICCS AU-55. Sorry for the auction house photo, I can't get to the coin at the moment.  |

1989 coin appears to have missed the aureate plating process.
The auction house pic of the 2006 coin looks to have a slightly golden color on the edge.
At the correct pH, an acid solution aureate plated Dollar can have the copper in the plating preferentially leached out, to leave a highly enriched, (but not pure) nickel plating left behind. Almost zero difference in weight.
I agree with john100.
IMO, both coins need further investigation.
Weight and XRF investigations would be would be a good start.

The Charlton Coin guide states that the Loonies were .915 nickel and .085 bronze, so that is a fairly thick layer of bronze.
If the plating is missing it should be a substantially lighter than the expected 7.00 grams.

I weighed it it's 7.10. I weighed another loonie of the same year and it's 7.09.
Don't know who to check with from here about it. & 🤷 #8205;#9792;#65039;

Now you need an XRF, most large coin or gold buyer shops will have one, it is an xray to find the coin's composition, if it is the same as a loonie this is unplated, if different most likely on a foreign planchet. Just pretend you want to sell it most shops will zap for free, Good luck!

Unfortunately we have lost access to Mr. Glassford"s error website, a few years ago a Quebec dealer offered a loonie struck on a Lebanon 1 livre 7gram nickel plated steel planchet which was struck by the RCM around this time period. Depending on an XRF this coin could be struck on this foreign planchet, this is all the research I can find at the moment Edited by john100
