<p>[QUOTE=&quot;GDJMSP, post: 2409387, member: 112&quot;]From what I have read, sometimes the edge or end of the strip can have a &quot;thin spot&quot;. So when a planchet is cut from there it has the corresponding thin spot. Depending on how big (meaning how long it is as measured around the edge) that thin spot is, or is not, the thin spot may be, or not be, &quot;filled in&quot; by metal flow when the planchet is struck. But if there is not sufficient metal to &quot;fill in&quot; the thin spot between the collar and dies by metal flow, the resulting coin can end up with a small thin spot with tapering ends like that exhibited on your coin.</p><p><br /></p><p>Could something like this also be caused by something like misaligned dies ? Yeah, I suppose so. But give the nature of the dies and the fact that they are machined to such tight tolerances, one would expect a thinner edge on a coin struck with misaligned dies to be less radical, to taper very gradually both left and right.</p><p><br /></p><p>In other words the edge of the coin would be noticeably thinner, but the change from thick to thin would be very gradual and over a longer distance, it would not suddenly dip and immediately go right back up like the edge of your coin does. </p><p><br /></p><p>I suspect that when you actually measure that coin, the edge will be the normal thickness everywhere except that one small spot. And were it due to misaligned dies this would not be the case for with misaligned dies if one side or the other is too close then by default the opposite sides must be too far apart - resulting in a coin with part of the edge too thick and the other too thin.</p><p><br /></p><p>But that&#039;s just thinking out loud on my part.[/QUOTE]</p><p><br /></p>
