You need to go to a gold buyer or good coin store that has an XRF and find it"s composition, then it will be easier to research and welcome !

What is the exact diameter of your coin?
Is it slightly smaller than it should be?
It appears to be smaller in your pics, the devices also appear smaller, if so it's most likely a genuine 2007 cent that's been treated to acid bath.

Ya I wish I lived closer to someone that could see this personally. Have no clue who can help with this unusual coin.. As for acid bath, don't think thats the case as its considerably smaller and the close up of the silver and copper penny pictures shows the real difference in the outside edges of the coin. The rim is different and the dots are further away. Plus the weight and width is too much of a difference to just take a few layers of plating off...least thats what I see

So you have ICCS look at this coin already and they say it is good? Some stores in BC must have n XRF with gold hitting record highs one fake bar or coin will cost half of an XRF machine

And its not gold thats for sure-its magnetic. Don't know of any XRF machines around here...most likely in Bancouver-which is about 14 hours away from me. Perhaps I could mail it. Just hate to loose it

I agree with DBM - this appears to be a normal 2007 cent that has been treated with acid. This removed the copper plating and reduced the thickness and diameter, with corresponding decrease in weight.

You are in a mining area I presume, would not a geologist or someone in this industry could XRF for you

"Acid" would also be my first assumption in such cases - if a coin is smaller, lighter and thinner than normal but still quite well detailed, acid is the usual answer.
However, my caveat would be this: once the plating on a plated-steel coin is removed or punctured with acid, the underlying steel should corrode and corrode badly. This does not seem to be the case here, since if corrosion is the cause it has corroded all nice and evenly - yes, it's pitted, but in my opinion not pitted anywhere near badly enough. I'm struggling to think of a chemical that's aggressive enough to shrink a coin by this much, yet passive enough to not instantly dissolve steel.
