I was just wondering, what year did Canada switch to Multi-ply steel coins? And what were the pre-Multi-Ply steel coins made of? (I'm guessing nickel) I ask this, because, although I'll likely get struck by lightning befor running into a Canadian half, however, if the previous coins were made of solid nickel, I would like to start keeping all of the Pre-Multi-Ply steel nickels, dimes, quarters, and if I run into any (yeah right  ) halves, and I have ran into some Canadian dollar coins, and my sister had a Canadian $2 coin in her till as a cashier at a local drug store she worked at, about 15 years ago or so, and I was wondering what a Canadian dollar coins and $2 coins are made of, before the Multi-Ply steel coins came out. (Oh, and just so you know, before the Multi-Ply steel coins came out, the Candian $1 coin was made out of a different metal than the center of the $2 coin. I know this because, the center of the older Canadian $2 coins did not stick to a magnet, while a Canadian dollar coin did stick to a magnet. So, what were these coins made out of?) Are pre-Multi-Ply steel dollar and $2 coins, as well as the other coin denominations worth keeping for their metal content? Edited by Fox

This is my somewhat simplified list of transitions. Canadian cents switched from bronze to plated steel in 1997. Canadian 5 cents switched from pure nickel to cupronickel in 1982, then to plated steel in 2001. Canadian 10 cents, 25 cents and 50 cents switched from pure nickel to plated steel in 2001. Canadian dollars switched form "aureate-bronze-plated nickel" to brass-plated steel in 2012. Canadian 2 dollars switched form an aluminium-bronze core and a nickel ring to a plated aluminium-bronze core and plated-steel ring in 2012. Quote:

That's why they're actively withdrawing them and melting them down.

Awesome, you've found a use for all that nickel!
What bugs me is that the mint is recycling a 100% nickel coin in order to........PLATE their news coins with a coat of nickel. What am I missing? Their supply of nickel for plating must be VAST!
For those wondering why nickel is used in plating, it has a great bonding property that makes it suitable for multi-ply applications. It's kind of "stickier" than most others, creates a better surface for other metals to bond.
I wish our 5 cent coins were not magnetic, as it would make sorting coins much easier if they weren't. :)

did not know about "Stickyness" before, TY Liber....That is a very important factor....For some of this we can think of US 25c Clad- they call it.....

Yeah, what's the deal with the steel and zinc pennies? Leftover planchets? Seems so random to have years with both, I wonder what the mint's logic was there.

The odd balls are of course the pure nickel 2001 25 cent piece and the 2006 cupronickel 5 cent piece.
I still wonder how the 2006 cupronickel 5 cent came about. Only thing I can figure is that they found old cupronickel sheets and said "Aw...heck...just use them up."

I think it's interesting that each denomination of plated steel coins has its own unique composition. For example the 10cent is 92% steel,5.5% copper, and 2.5% nickel, while the 25cent is 94% steel,3.8% copper,and 2.2% nickel. This was done to aid the vending industry in identifying coins by their electromagnetic properties.

Ah, now I understand what they mean by an electromagnetic signature.

DoubleEagle20: lol, I´ve found this to be true of Zimbabwe hyperinflation notes as well. If you look at the watermark of certain notes you´ll find that some of them bear the $1000 watermark, being that inflation rose so fast that they had leftover stock paper that they had to use up. For a while I thought I had a fake note but I cleared it up with my dealer.
