<p>[QUOTE=&quot;Kevin Mader, post: 7513674, member: 106826&quot;]It&#039;s not uncommon to get to sections of a coil of material where it is thinner/thicker than other areas.&nbsp; I suspect that for coinage, the controls would normally be tighter than for commercial jobs/products.&nbsp; Coin operated equipment in part, relies on weight.&nbsp; Coils can be rather large relative to the optimal layout, determined hourly rates/yields, etc.&nbsp; So while the sample or outer bands may be sampled for inspection, inner portions not so much.&nbsp; It&#039;s possible, indeed likely, that at some point, the planchets are thicker/thinner...heavier/lighter than the others in that coil.&nbsp; Most will be in the tolerance range, but some will be outliers.[/QUOTE]</p><p><br /></p>
