No plating,it's cupro-nickel.
"Dipping" is not considered cleaning...

Cupro-nickel is an alloy of 75% copper and 25% nickel.
2006 nickels with no p or no logo are not plated,they are made of this copper-rich alloy.
All nickels from 1982-2001 except 2000p and 2001p are cupro-nickel.
Pre-1982 nickels are 100% nickel.
All 21st century nickels,with either the p or logo obverse mark are made of plated steel.

Looks more corroded than anything.. But if you wait and see if SPP-Ottawa chimes in, or send him an email. He does do studies on nickels with excess copper in them as a few have been found and tested by him... I believe those ones are completely colored differently, this one appears very spotty.

I'd say you found yourself a fountain coin as you can see where another coin laid on it. I have plenty of these as I bought a whole bag of them just for fun.

No. It is NOT a plated steel 5-cent, DBM already explained that. It is one of the 2006 "no P' 5-cents, struck in cupro-nickel, the last Canadian circulation 5-cent to be struck on a solid alloy.
It is not a copper-rich alloy or anything else, the green-blue deposits on the coin are copper oxides (almost looks like azurite or chrysocolla) due to oxidation of this coin, from being in wet conditions. To simplify it, oxidation = corrosion. The explanation of a 'fountain coin' is a good one. Spend it, or make a wish and toss it back in a fountain...
