<p>[QUOTE=&quot;Conder101, post: 4585367, member: 66&quot;]How did you determine it isn&#039;t a rolled thin planchet?&nbsp; Minimum weight for a cent blank is 2.98 grams which would have a theoretical thickness of 1.176 mm.&nbsp; A 2.88 gram blank will be 1.141 mm.&nbsp; A difference of .035mm (or just over 1/1000 of an inch)&nbsp; I doubt you could see that difference if you were looking at the edges of the blank.&nbsp; Once it is run through the upsetting mill forget it, and after striking even more so.&nbsp; As I have said many times you can&#039;t judge the thickness of a struck coin by looking at the edge.&nbsp; The edge thickness is more a function of the strength of the strike than the thickness of the blank.&nbsp; </p><p><br /></p><p>This can be demonstrated by looking at a proof coin.&nbsp; The proof and business strike are both the same material, same weight, same diameter, same starting thickness of the blank, the only difference being the striking pressure.&nbsp; But the proof coin, struck at the higher pressure will appear thicker when viewed at the edge.&nbsp; Likewise a well struck thin planchet can be thicker at the edge than a less well struck normal planchet.[/QUOTE]</p><p><br /></p>
