Green IH penny

I came across this green IH penny, it's in great shape, just green. This isn't normal toning is it? Maybe wrong planchet or a type of PMD? What do you think

1. Can you take a picture against a neutral (gray, black, or white) background? The hot pink makes it hard to tell what color the coin really is.

2. Verdigris, a type of corrosion affecting copper, is green. If you find a green cent, that's almost certainly what it is.

 

Hope these pics help... The " hot pink " is actually the back of the official red book for coins ( slightly sun faded)

 

IMO it's oxidation/corrosion.

 

Might be a metal detected coin, the IH cents I found look like that.

 

It looks like corrosion.

 

Looks like just about every copper roof in the country.

 

Which goes under the general term "verdigris".
A quick check indicates that it is most often copper carbonate, copper chloride or copper acetate depending on the chemical environment it was found in.

 

I found a few with my MXT that had the same color last year....
