That's heavy Die Deterioration (Die Attrition)
That's not completely true, and your linked pic, Crazyb0, is guilty of this as well. Yes, wear to a die can be called "attrition." However, in distinguishing the types of effects on dies in use, "die attrition" is reserved and not equal to "die deterioration".
This is die attrition:http://www.error-ref.com/die-attrition-error/
It is a specific result from a malfunction of the press or the alignment of the die in use. Die deterioration, on the other hand, is a normal part of minting coins over time. The two should not be confused.
