<p>[QUOTE=&quot;Conder101, post: 2034973, member: 66&quot;]The edge is applied to the circulation strike coins AFTER the coins are struck by a method similar to how the edge of the blank is thickened to create a planchet.&nbsp; The coin is rolled between a roller and a roller die that contains a groove in it. At the bottom of that groove is the RAISED edge inscription for the coin.&nbsp; As the roller die turns the coin rotates and has the inscription pressed into the edge.</p><p><br /></p><p>If the coin doesn&#039;t go through the roller you get a plain edge dollar.&nbsp; If the roller isn&#039;t placed close enough to the roller die you get weak or partial edge lettering.&nbsp; If the coin does not roll smoothly you get unevenly spaced edge lettering, or some missing letters, or in extreme cases the coin can stick and the letters in the die going past can scoop a gouge in the edge of the coin.&nbsp; If the coin does not get ejected after one rotation you can get doubled or even tripped edges.&nbsp; If he coin get edge lettered, ejected, an then somehow gets back into the machine you can have doubled edge lettering with a wide offset between impressions, or if the coin get put in upside down the second time you can get two sets of lettering one right side up and the other inverted.[/QUOTE]</p><p><br /></p>
