I was passed this information and thought it may help others, for those interested there is a ANA Course on the Modern Minting Process, Errors and Varieties, and various on grading coins. An eroded die is one that has been used extensively to mint coins, the the surface of the die is showing great wear. The letters are "spread" or distorted towards the rim. The outer edges of devices or lettering is not sharp, it has eroded to a ramp-like edge.There are heavy die flow lines, less detail on the devices, and distorted lettering towards the rim. The first picture is of an average 1987 dime. The second picture is of a 1987 dime from an eroded die. I hope this helps others who are new to this like me and need detailed information to be able to understand the meaning of an eroded die. Happing Hunting
Now that is "good stuff". How often does someone come here with a question, get a couple of answers that don't make a whole lot of sence to them, and wind up doing research which leads to posts like this? Well done, survivor. You make my time, that I spend on these forums, seem like it is not in vain.
