<p>[QUOTE=&quot;Conder101, post: 3044382, member: 66&quot;]After a coin is struck, the anvil die rises to push the coin out of the collar (actually I&#039;m not sure if the die rises or if the caller is pushed down. Frankly pushing down the collar makes more sense to me.) When the end will die retracts sometimes the collar sticks not allowing the anvil die to retract fully. This results in a coining chamber that is shallower than it should be. When the planchet enters the coining chamber it now extends above the surface of the collar. When it is struck you get the reeding on the lower portion of the coin and the upper portion of the coin is left blank and sometimes spreads out above the surface of the collar. This is a partial collar strike, sometimes called a railroad edge.</p><p><br /></p><p>If the collar sticks more on one side when they anvil die retracts, the surface of the collar may be tipped relative to its normal position in the coining chamber is more shallow on one side than on the other. A coin struck in such a coining chamber may have nearly full reeding on one side and only partial reeding on the other. This is a tilted partial collar strike.&nbsp; The OP coin matches this.[/QUOTE]</p><p><br /></p>
