It starts as a clipped planchet; the blank before the dies in the coinage press strike it. A punching-cutting machine is used to make the planchets. Long rolled sheets of metal are automatically fed into the machine and the punching-cutting machine goes up and down, cutting circle planchets out of the thin metal strips. If the metal sheet is not lined up properly with the punch-cutting machine, straight clips can be formed. This is because the metal is feed into the machine to far to the right or left. The punching-cutting machine will cut circles out of the sides of the sheets, which do not fill the area cut by the punch. This leaves one side of the planchet straight. Thus a straight clip.</p><p><br /></p><p><img src="https://www.fleur-de-coin.com/images/Thumbnails/errors-clip_double_straight-SIZE150x150.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> <img src="https://www.fleur-de-coin.com/images/Thumbnails/errors-clip_straight-SIZE150x150.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> <img src="https://www.fleur-de-coin.com/images/Thumbnails/errors-clip_straight2-SIZE150x150.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p>If the metal is not feed into the punching-cutting machine at a steady speed, the movement of the metal does not keep up with the punching. When this happens, the machine is cutting circle planchets out of an area in the metal that has already been cut. This a curved clip. If the roll of metal over feeds the punch-cutting machine, the punching machine cuts the ends of the roll. This forms ragged clips.</p><p><br /></p><p><img src="https://www.fleur-de-coin.com/images/Thumbnails/errors-clip_curved1-SIZE150x150.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> <img src="https://www.fleur-de-coin.com/images/Thumbnails/errors-clip_double_curved-SIZE150x150.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> <img src="https://www.fleur-de-coin.com/images/Thumbnails/errors-clip_ragged2-SIZE150x150.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p>The chart below is intended as a representative example of what might occur to cause incomplete planchets. In actuality, the planchet strip is up to 18&quot; wide, and gang punches may have up to 80 dies to punch the blanks. The numbers in the diagram are meant to represent 5 actions of the punch. The first, second and third are normal. The fourth punch has slipped (likely due to a loose guide), causing the punches to overlap the edge. The 5th punch also overlapped the edge, and overlapped the end of the strip as well. As you can see by the drawing, these various misaligned punches cause the incomplete planchets described above.</p><p><br /></p><p><a href="https://www.fleur-de-coin.com/images/articles/errors/clip.jpg" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.fleur-de-coin.com/images/articles/errors/clip.jpg" rel="nofollow"><img src="https://www.fleur-de-coin.com/images/Thumbnails/errors-clip-SIZE296x160.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></a></p><p>With clipped-planchet errors, size matters-and so does the number of clips. On average, a statehood quarter with a single clip is worth about $50 to $60. It would be worth $75 to $100 with a double clip, $100 to $150 with a triple clip. A coin with particularly dramatic clips, or with more than three clips, could be worth even more. Conversely, a coin with relatively small clips could be worth substantially less.[/QUOTE]</p><p><br /></p>
