Either a die gouge or a slight die dent. Not a variety, just a die event. How dos this happen. Keep in mind the location of the damage? It is on the fields. On a die the fields are the outside edge of the die:

When looking at a die, the fields are the outside part of the die. The devices and design are incuse into the die. The step down on the outside edge of the die is what I call "The gutter.


This helps form the rim along with the collar that shapes the outside edge of the planchet. (Some coins are flat edged, and other have reeds, the collar determines which is which) The planchets are a bit smaller than the collar, when struck the planchet is struck and stretched into the collars allowances for the outside edge of the coin. (back to the die issue)
The dies are often rescued from die damage. This is done in a different location at the mint:


They polish off clash mark damage,
Feeder Finger Damage and if during the process, the die gets scratched, what area will be affected? The fields. So rough contact can a alter a field leaving a die scratch, gouge while the dies are handled. If a die is dropped onto another die, it will leave a dent.

On what area? Again the fields are affected. So note on the image above, just the fields are affected. Even fields near the rim can be affected:




So these are just die events. The die was normal until the die was altered. So it is not a die variety, it is a die event. Just like if we fall and get cut, we would have a scar. That would be a life event. Well to a die, when something happens to them that affect the life of a die, they go through events as well.

Die is a die event? How can die gouges and die dents be caused? Are these normal events?
