<p>[QUOTE=&quot;Conder101, post: 791464, member: 66&quot;]I would say they are not adjustment marks, but I would also say that they were in the planchet before striking.&nbsp; They are not post mint.&nbsp; (In the early years adjustments were made by file across the face of the planchets but in the later years when planchets manufacturing resulted in planchet weights being closer to tolerance, adjustment were normally just done as touch ups on the edge of the planchet.)</p><p><br /></p><p><br /></p><p>Actually the adjustment marks show up more strongly on the devices.&nbsp; Since the fields are the highest parts of the die they make contact with the adjustment marks first and then crush and flatten them as the fields are pressed into the planchet.&nbsp; The marks in the area of the devices are subjected to less pressure, and in some cases the die cavities do not even fill completely so the adjustment marks in those areas may receive NO flattening and show strongly.&nbsp; In fact ne way to tell if marks were in the planchet or if it is post mint damage is to look and see if the marks run all the way down the devices to the field and whether they are visible in a crushed form running across the field in protected areas.&nbsp; On post mint damage the marks typically do not go all the way to the edge of the devices and field.&nbsp; The marks stop and jump across the protected field area to the device on the other side and does not touch the junction of field and device there either.[/QUOTE]</p><p><br /></p>
