Welcome to the forum. Unfortunately, everything you see on your coin is damage. I call it a parking lot cent. It is junk.

The blue-ish color you see is the exposed zinc core due to the holes in the copper plating.

Hello Jonnie and welcome to the LCF! Here is the definition for what Will is explaining about the odd shaped circles you are seeing on the coin and at the mint mark. It is zinc rot - not a very pretty name I know, but that is what it is. Also the reason it is called a "Parking Lot Cent" is because it has been severely damaged (like being run over in a parking lot). Even the edges around the rim of the coin have been damaged.

Zinc Rot: Zinc corrodes easily when exposed to the environment. When the plating is split on a copper-plated zinc cent, the zinc will often corrode under the plating, and push up on it creating a bigger and bigger fissure. Due to the strength of many of the hand-punched mint marks on pre-1990 business strike cent dies, this is a very common place on Lincoln cents for the plating to split and for this corrosion to take place.

If you click on the link below it will take you to the Glossary Page, scroll down to "Zinc Rot" and click on the photo to see a good example.

This is what happens when zinc cents (ones from mid 1982 to now) get exposed to moisture for a while.
The zinc grows oxide wherever it gets exposed, the oxide pops through the thin copper plating and pops like a pimple and you see the zinc or zinc oxide exposed.

Someplace on here Coop has a pic of the way they fail that matches yours, the mintmark sinks into a pothole then falls off altogether.

Ed, that photo of Coop's that you are referring to is the same photo I linked to above. It's in our Glossary
