<p>[QUOTE=&quot;Dynoking, post: 26020855, member: 81795&quot;]When a planchet is struck by the hammer die the metal flows into the recesses of both dies (hammer and anvil). If the device has a high relief the metal may fill the device leaving less metal for the reverse.</p><p>A popular coin that has this issue is the Jefferson nickel where as the obverse device void in the die fills and doesn’t leave enough material for the Monticello mansion on the reverse leading to a poor reverse strike.</p><p>The LWC is probably best example of poor metal flow. Mr Lincoln’s bust had a very high relief the results in a poor strike for the E in ONE and the C in CENT. </p><p>Planchet thickness, die spacing, strike pressure, strike speed, and die condition will also influence the metal flow between the dies.[/QUOTE]</p><p><br /></p>
