SPP-Ottawa Moderator Canada 10460 Posts	Posted 07/08/2013 11:12 am The improper alloy coins we studied were the Cu-Ni coins from 1982 to 2000. Prior to 1982, Canadian 5-cent coins were basically 100% nickel. The first question I would ask, is the coin attracted to a magnet?

nickelsguy Pillar of the Community Canada 2301 Posts	Posted 07/08/2013 5:08 pm I have seen "toners" of 100% nickel that looked like this. Report this Post to the Staff
nalaberong Pillar of the Community Canada 2805 Posts	Posted 07/08/2013 5:33 pm It's probably just gunk. Never underestimate the disgustingness of coins - I've seen more than one eyelash stuck to the same nickel... Report this Post to the Staff
SPP-Ottawa Moderator Canada 10460 Posts	Posted 07/08/2013 6:05 pm Pure nickel coins generally don't tone that colour... I would be willing to test it for you. Once you get to 50 posts, send me a PM.
