Yet Another Question - About Die Markers.

thanks for the response, but that wasn't the question. I am already convinced that I have identified the coin properly. the question was if those same die markers, which were an exact match, to the markers at coppercoins website, could they ever be present like that, and NOT be that exact coin. for instance if there were some reason that the "D" wasn't completely visible, or identifiable. could the presence of ALL of the matching die markers - be conclusive?

RPMs go through various die states as well. The punching may enlarge/ get stronger or in some cases and in other get weaker with die use. Here is an example:

Die markers must match exactly. In this case it helped to identify this coin. But not all die markers remain the whole life of the die. Some die scratches may only appear on early die examples, while die cracks/chip/breaks continue to worsen with continued use. Die gouges may remain longer or remain the life of the die. Die scratches in the fields may flatten with time. I like to call them as "faded" die scratches as they are still in the same area on the die, but disappears in the field, but may remain stronger next to devices. Clashes may be polished out leaving more wear on the die. The devices get mushier as continued use wears the die. Something of note is than not all obverse/reverse die pair may not remain to the same age. On of them maybe replaced if one get broken. Ofter another die is paired that may/may not be of the same die state. Some times a new die will start if venture on the coin making events it faces, other times a semi-retired die may be placed back into use.
On a different note though, the dies often face the same events that change their appearances. Die clashes/cleaning/gouges alter the true design some and happen several times during the die life. Die crack appear in the same places because of the continuing clashes. Designs of the coins may be weaker/poorer in design may leave a common defect. Often you find cracks in certain areas, Head, Shoulder, columns edges of the memorial or at the roof or cornice tips. Common because of the same events happen over and over and the coins they make are almost identical.
So die markers may come and go or remain the whole like of the die. Hard fast rules seems to not always apply. So first identify the variety by location, spread and lastly markers to identify die states as a confirmation. Looking for markers first and assuming they are from that die will not work because of the repeating markers on normal coins. So ID must be exact of markers LAST.
