As noted on another older thread, I've been pulling a few coins off the TD Bank counter magnet about every time I do a penny dump. It's an international smorgasbord, with coins from about every country. Of course quite a few Canadians. And the occasional steel war penny.
I'm a bit slow on the uptake, but just today it all clicked and I realized that most of the Canadian coins I'm pulling off are not the newer steel coins, but are pre-2000 coins, and therefore are .999 Ni. Awesome. Since they are "free" to me, even the dimes and quarters make sense to keep just for the nickel. Wish there were a few more of these counters around here - I've only got the one within driving distance.
