Hey Canadian coin people,
I was just looking at my 2012 base metal 2012 Canada proof set. As you may know, the quarter in this set is supposed to be composed of nickel (as are the 5, 10, and 50 cent coins). They are all appropriately magnetic except for the 25 cent piece. Does anybody know why this might be? At the very least, can any of you confirm this observation?
Thanks in advance,
Bruce

Maybe someone slotted a Silver Proof into the set by accident?
Did you buy the set straight from the mint?
What is the weight of the 25 cent?
EDIT: Actually, dont take the coin out of the set. Hard to get coins back into the case and stay once they have been taken out.

I suppose that it's possible that it's silver. However, it looks similar to the other nickel coins. It is my understanding that the fine silver version of these proofs look noticeably better.
I did not buy it straight from the mint, but I feel pretty confident that it has not been tampered with. It still has its box and CoA and is in pristine condition.
No, I will not be taking the coin out of its case. :-)

 Please post pics of your set so we know what you are talking about. "Dipping" is not considered cleaning...

Yes, that is the set in question. Thanks for checking your set. Given that yours is magnetic, either mine is so weakly magnetic that I can't notice, or something else happened. My set is 07542 (of the 40,000). What number is yours (it's indicated in the CoA)?

You're welcome. My COA # is 11034/40000. I checked again, using just an ordinary fridge magnet the 25c, 10c and 5c in my set are equally magnetic through the hard plastic covering. Yes indeed, perhaps your set contains a silver quarter. 2012 was the very first year for the two different types of Cdn proof sets - silver dollar only or complete silver set and it could be possible your 25c was added from the other type of silver set in error. Looking at a visual comparison between a proof nickel and a proof silver 25c, unfortunately I don't notice any real difference in general appearance.

without pulling the coin out and weighing it and or having an XRF to determine the composition, it may remain a mystery.

In fact I did reach out to a geoscientist. He said that if it is in a 1/16" or 1/32" solid plastic "window," then it is virtually impossible to get X-rays in and/or X-rays out. Also, "Assuming it is "plastic" and of some thickness more than a few microns or tens of microns, I doubt that any 'normal' XRF device could be used to determine the elemental composition."
I guess the specific answer as to why a magnet doesn't attract it will remain a mystery....

You can easily open the plastic case and reclose it. Its resealable

I've a couple of sets I want to take apart so I can take out the coins for my collection. Although I haven't looked closely, I assumed I'd need to somehow break open the case. Care to share your knowledge? |

It appears that wilsonwu89 is correct. It appears that I can just pull it open. Hmmm.... Perhaps I will check back with that geoscientist....

That easy? Well that's certainly good to know. I assumed, worse case scenario, I'd need to tackle the job with a pry bar and hammer  |

How hard is it to release the loonie from the NHL mini-pucks?

The mini pucks I had to cut the edge with a band saw and break an edge off to expose the coins edge. Then carefully pull/lifted it out. The problem with the mini pucks is there is a small magnet to hold it in place. I will have to check my 2012 set quarter!!

On the mini-pucks, it is that magnet that often scratches the obverse of the coin. I tore apart at least a dozen Vancouver Canucks mini-pucks, before I found a loon that would certify MS-67 with ICCS...
