Conder101 Bedrock of the Community United States 17884 Posts	Posted 08/12/2008 10:17 am I thought die wear doubling was typically seen on the outer edges of the lettering, away from the center of the die Report this Post to the Staff
seattleMD Valued Member United States 405 Posts	Posted 08/12/2008 12:12 pm conder101 - Based on the samples I have seen, I believe there are two main types deterioration. Here's my speculation on what causes them. Keep in mind I'm far from a metallurgist. When the die strikes the planchet, metal flows from the planchet into the devices on the die and across the field of the die towards the rim (and the collar) as these are the areas of least resistance. As the metal flows into the devices on the dies, it wears away the edges of devices closest to the field as well as the field immediately surrounding them. This would cause the Die Deterioration we see in this sample. Once the metal fills the device, it then heads towards the next source of least resistance which would be rim of the planchet. As the metal flows back out of the device and over the edge of the device closest to the rim, it causes that edge of the device and the immediate field nearby to wear away. This would be an example of what you are familiar with as the affected field would be the area between the edge of the device and the rim. I'd be curious to hear how far off I am if someone knows exactly what is happening - again, mine is just a theory. Report this Post to the Staff
