You need to learn how the minting process works and realize the infinite possibilities of how someone could damage a coin.
Really? You believe that? A single pair of dies strikes millions and millions of coins. If what you believe were to be true, why have only two coins, out of the millions struck, been found?
There are hundreds of ways a coin can be damaged, but zero ways that could have happened at the mint. Read up on the minting process and it will be clear that it would be impossible for it to have left the mint like that.
The OP's coin, from 5 years ago, is badly damaged, and is not an error coin of any kind or type. There are lots of modern cents that have been damaged like that one, and look almost identical. Your coin is one of them, if you're saying it looks like, or close to, the OP's coin.
I have a coin kind of like that. everybody called it a "half dryer coin" because only half of the coin looked like, well, your 2005 penny. And that was the end of it. At that point, I decided that since nobody thought it was an error coin, it was probably nothing. But now that I see your coin, I'm mot sure. on the front of the coin, it looked the same as yours. On the back though, it looked like a normal penny. Here's a picture of it. I noticed the words and parts of the designs are underneath the rim. So it can't be wear. Nobody knows what caused it, and they all agreed that it was pmd. So I left it at that. It was kind of disappointing, but I couldn't prove that it was an error. My point is that nobody is going to know what it is that happened the it. You can call it an error if you want, but that probably won't change anyone's opinion on it. The only possible way to find out for sure that it's an error is if you can find a coin that looks just like it. But hey, maybe some person will pay you a couple dollars for it.
Think about it, if parts of the design are under the rim, then the coin had to have been struck before the rim was pushed out over the design. Hence, post mint damage.
@Barnabus, it's been 5 years now. what were the results of your Heritage auction? Yeah, that's what I thought.
As a new member all I can say is use the referenced coin sites to learn about the minting and die process that causes true errors that create the value... If not in dollars than for your your own "hunting" experience. What I see in the photos are worn coins beat up through use and exchange. ~Rob
Sorry, but your coin is not an error, it's damage. The copper plating around the rim was worn/abraded away and the underlying zinc core has corroded, The copper core is only approx. 8 microns thick and once it's broken through, the zinc can corrode like the steel in the fender on your car if it's scratched.
Looks like the zinc is rotting out from under it. Biodegradable currency. This one lasted only 15 years. That's about twice the lifespan of a new modern day car actually.
Sorry if I upset members. I wasn't calling it an error or anything else. I was just posting a picture of damaged coin that I never have seen in 50 years of collecting.
You won't find zinc rotted pennies with dates before 1982. Before that date, pennies were actually built to last. I can find pennies from the 60's in my everyday pocket change that are in better shape than pennies in the same pocket change from the 90's and newer.
Why is this penny got missing Cooper is it just wore or did it come out like that. The surface is smooth but none of the letters or date is wore off u can see the letter plain as day.
Your coin has been ground down revealing the zinc core underneath the copper plating. Spend it before it rots away. Also, welcome and be sure to make your own thread if you have a question about a coin instead of hijacking someone else's thread. Especially one that has been dead since October.
