coop Bedrock of the Community United States 62064 Posts	Posted 12/26/2016 3:20 pm 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.

CoinMasters Pillar of the Community United States 5964 Posts	Posted 12/26/2016 3:50 pm 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. Edited by CoinMasters 12/26/2016 6:01 pm Report this Post to the Staff

CoinMasters Pillar of the Community United States 5964 Posts	Posted 12/26/2016 6:52 pm 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 Report this Post to the Staff
CoinMasters Pillar of the Community United States 5964 Posts	Posted 12/27/2016 10:48 am 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? Edited by CoinMasters 12/27/2016 12:19 pm Report this Post to the Staff
