<p>[QUOTE=&quot;desertgem, post: 2361300, member: 15199&quot;]The thickness of the strip used for punching planchets were determined by using rollers to slowly approach the thickness needed ( using a dial indicator) so as after several annealing passes, and using a standard punch would produce a planchet within the tolerance of a morgan weight. The collar would allow little change in diameter, and if the planchett was the correct weight ( within tolerances), the height of the coin would also have minimal variation. Only the weight had the tolerance dictated by law. If the die distances were slightly inaccurate, the die features might cause a slight variation in height, but since they were set and reset after die change, there would be difficulty determining tolerances by law. After all, the purpose then was the value of the weight of silver&nbsp; and not variations ( errors) so prevalent today.[/QUOTE]</p><p><br /></p>
