Message:: [QUOTE="Clawcoins, post: 4876940, member: 77814"]With Die Deterioration think about a flat planchet. When it is struck by a die the middle metal gets pushed up into the design elements. Extra metal gets pushed out to the sides, scraping everything along the way. The outer elements normally get worn much more than the inside design elements because they get more metal pushed their way which scraps the metal and the 90 degree edges of the elements all get worn out and edges broken off.   Thus you get stuff that looks like your dime. With the Below Image and yellow circles, Think of the metal from from the direct center with radial lines going out to the edges.  Notice the lack of a clear edge on the bottom "O" of one.  The die "O" inner edge was worn away by metal flowing over it from each planchet.Thus it is not as well defined as the outer part of the O in this example, as the inner part took the brunt of the damage. On the "U" above it you can see how the outer edge of the long side of the "U" too a lot of element edge damage from metal flow, thus extended the upper edge of the "U".Then add to it all the metal flow wore away on the entire flat part of the die surface, thus you get striation lines and other surface irregularities so the depth of the elements is less than a brand new die .. kinda like a car tire when it gets worn. then add grease which fills in areas and does not let metal flow into it.[ATTACH=full]1177931[/ATTACH][/QUOTE]
