Message:: [QUOTE="Clawcoins, post: 4110883, member: 77814"]Also if you look at extreme cases of die wear you have these examples: Die flow lines where the metal flow has etched away the flat surface of the fields, thus you end up with this which gets worse as you get close to the edge.[ATTACH=full]1067110[/ATTACH] here the "depth" of the letters have been worn away and the metal has elongated the letters.[ATTACH=full]1067104[/ATTACH] on the OPs coin you have this[ATTACH=full]1067114[/ATTACH]You may notice:<ul> <li>on the right side where there is no lettering, there is no ridge ring.  This is common as the metal has no letters to wear out the edges.  So a ridge ring would normally form coming into this area from the top.</li> <li>On the bottom where the lower part of the bust is the metal mostly flows into the bust thus a low pressure zone.</li> <li>many times you'll see the "doubling" on the date/mm too as it has edges to wear out.</li> <li>the top and left contain most of the wear in this instance (with the IGWT letters).  Maybe it is due to the die not exactly being totally flat too.  unknown. But the pressure is wearing the edges then starts extending around until the pressure is relieved (bottom of bust).</li> </ul>Remember the Hammer Die is the obverse .. it is the one hammering super fast.  Thus the reason the reverse with the anvil die doesn't normally have ridge rings. So this is all die wear.[/QUOTE]
