Interesting in that there were a few folks who knew not what they were looking at, yet still displayed a desire to know, beyond the boundaries of attribution and value.
Eventually culminating in a discussion between an engineer and a physicist, the gray area between the how and the why, the macro and the micro mechanics of the planchets, yet no discussion whatsoever of the force that caused either this plasticity and molecular crystallization to occur. The characteristics and properties of metals is required study for certain areas of both fields, and should not be confused with metallurgy.
It is my belief that gaining an understanding of the causes of specific phenomena on a coin would naturally enhance the overall collecting experience.
I have never seen such a coin as is referred to, but would be highly interested in doing so. Are there some nice photos somewhere?
