<p>[QUOTE="ken454, post: 1893178, member: 56575"]the thickness is not present in other areas because the die is not wearing out evenly, it wears at a molecular level with many variables such as die hardness, planchet hardness, improper annealing, type of metals to name a few, all affecting how a die will deteriorate...</p><p>what you see on the "E" is die deterioration doubling, When the dies strike the planchet to form a coin, the planchet metal is pushed into the cavities of the die to form the design.The constant movement of planchet metal across the surface of the die causes the die surface to wear and erode as time goes by.The eroded areas on the die are depressed, but on the coins they appear as raised areas.Since the greatest erosion is around the design elements such as the letters, date, etc. the new raised areas resemble doubling. it is not a doubled die... your coin also shows radial flow lines, a dead giveaway of die deterioration...[/QUOTE]</p><p><br /></p>
