On the rev only, three areas of concentrated radial marks. Is it indicative of worn die stress, late stage tool marks to extend the die wear or something else. Need your input. Thanks. Peace
Looks like late die stage die erosion
To me. Like they ran the die to death, or cancelled, which came soon after this I imagine.
I am not an expert at all on these matters, I just have read a lot and looked at old die states like this, so I assume LDS erosion.
Thanks for opening them up. I agree. just read that radial flow lines are a sign of die deterioration. I'm learning! Peace Roy
@Namvet69 What is the large, deep radial line between the "M" and "E" in the middle image called?
Why that's pmd! @Insider2
