Thanks mike. Awesome find, would this one be extreme enough to warrant a premium?

I would think so. The one I found years ago was mild compared with this one.  |

Hi Bella57,
I think we have the exact 1990 Nickel coin look a like.
Hi Mr. Mike, can the same Die Attrition be found in another coin of same year?

Please advice if this going to hijack the thread so I can remove. But one thing for sure I want to understand the way it is happened. Similar Die Attrition present on same location of the same year coin. http://goccf.com/t/273996  |

If the die is worn then I don't see why there wouldn't be multiple examples, same year, same die.
Very interesting to see two examples back to back so quickly.

After the damage was done, then all coins struck with that die will show this error. Your coin is no doubt from the same die.  The miss-alignment of the die, made it rub on the collar. It removed part of the outside of the die on that area. It didn't all happened from the first strike. It was over a period of time that this contact was happening to the die and wore off the outside edge on just that area. There could be a few or several hundred thousands of them. Until it was noticed it may have been used. Some coins are struck very fast. I remember reading that 12 per second could be struck on some coins. So it is not a slow process. The damage to the die may have just taken seconds to happen. Edited by coop

Then I suppose it's correct to say that any coin showing MD due to an over-used die is a die attrition error as well. That would include Ghosting errors, progressive Beehive cents, and others.

MD can happen even on doubled dies. So it can affect the strike of any die, normal or what ever happened to the die during its life.

No. MD can happen on any die, but MD does not create die attrition. What causes die attrition is the miss alignment of the die setup so that is hist the collar. wearing off the outside edge of the die. That is why it is only affected on one area of the die. All coin struck with that die, will show the same affect until the die is retired. So if there is die attrition on the die, it will show on every coin. And it can show machine damage if the machine is strike causes a bounce. It not, the the coin will just show die attrition. MD does not cause the issue. It is a altered die issue.

Okay, I'm wrong and Coop you are right. I had looked up attrition when I should have looked up die attrition. Very sorry last time for me.

Not a problem. I've been incorrect (never wrong LOL) sometimes also.

You're a heck of a good man Coop. I owe you a lot. Sometimes I wonder how you put up with me. I promise the next time I go off on a tangent I will be 100% correct. lol

I realize I could just let this thread sink to the bottom, maybe I should as it made me look foolish. Of course I can't do that though. Coop, I have known for a long time now, you are correct around 99% of the time. I can't help it, but I take very little at "face value" ; the way I learn is to question. What I need to learn is to fact check and then question. I have done that now. What I think I have learned is the Die Attrition error. I have one more question on this error.
What I think I know is the Die Attrition error can be a form of Peripheral Die Damage. It's caused by a misaligned die repeatedly hitting the collar causing wear on the die and then returned to center. I also think I know die attrition is the process of die erosion due to repeated contact with other surfaces. What I think I know, is there are a variety of other errors with different names caused by die attrition. If I'm correct so far, my question is why is the one on Error Ref. com is called the Die Attrition error?
