Again I am not sure what to make of not getting any reply? Perhaps no interest? Maybe insignificant?
However digging further I ran into the following (at the bottom of the page in the link below):http://coinscan.com/err/mont.html
the above is at Patrick Glasford's website and showing the condition as tool damage.
The only thing is that the condition I have is only on one side so it cannot be both dies clashing against the tool.
There is also some die deterioration on the "O".
So I am lead to believe that the whole thing could be some sort of deterioration with a die developing a large and deep uneven crack. Does that sound plasuible?
