Hello Everyone I'm new and have a few coins I'd like to share

I have been collecting the error coins for about 5 years. I enjoy them most of all but I do have other coins and some currency and a few confederate notes also.
Most of my error coins are pretty common varieties, Double dies, broad strikes, and defective planchets. The ones most everybody acquires over the years.
I do have several however that are kind of a mystery as to what they are and how they came about. If it's okay, I would like to post a few pictures over the coming weeks and gather some opinions from people who has a lot more experience than I do.
My first coin is a 1943 steel cent that is covered with, for lack of a better word corrosion. Maybe more like oxidation. Its hard to get an accurate picture of how beautiful and sparkly it is with an ordinary camera and a magnifying glass. It's the only one I've ever seen. Any ideas?

Environmental damage. Welcome to Cointalk.

 

Welcome to Coin Talk.
You hit it on the head. Corrosion. It happens to most 1943 Lincoln Cents. They are made out of steel and coated with zinc. As the coin circulates corrosion occurs. My suggestion is you get a Lincoln Wheat Cent coin album from Whitman and let this be your starter coin. As you make your coin collecting journey and fill the album you will find a '43 in better shape to replace this one.
Happy collecting, and remember the fun is in the hunt!

 

Hello. The correct Numismatic terminology is actually Doubled Die, not double die. Big difference..

Look at this website with the explanation

Agree with all, environmental damage/corrosion.
Invest in a copy of the Red Book.

On steel vents that is the way they look when suffering from environmental damage. Welcome to CT.

 

Chemical corrosion, worth 1 cent now.

 

And worth less than that in the future! lol

 

Thank you all for your input. I was pretty sure that was the case. It came from an older source and the zinc must have had time to oxidize and cover the coin. Maybe someone dipped it or polished it and that's what started the chemical reaction. I had never seen another 43 like it and a quick search didn't turn up any clues. Google is handy but not a lot of fun anyways. That's what lead me here.
Also, thanks for the website that explains doubled die. I got the hang of typing it pretty quickly. But when I say it, it still comes out double die. I'll keep practicing in my spare time though.
Here is another one that I'm not sure what it is called or what caused this error. It's one of my favorites

 

Just PMD Sherlock.

 

A 1943 cent is made of steel, not zinc. That’s why they rust. The other coin you showed is damaged as well. If you’re really interested in coins you can learn a lot with us.

 

The post in #9 doesn't appear to be an error. (Someone will be able to tell you exactly what it is.) An error happens at the mint. Whatever happened to this coin happened post mint.

 

It's known as a dryer coin.

Dryer coin + verdigris = worth 1 cent
