<p>[QUOTE=&quot;cvicisso, post: 1358319, member: 29382&quot;]Anything over 226g <i>might</i> have silver in it (on my scale at least).&nbsp; Over 228g - definitely has silver.&nbsp; Over 229g has a 90%er in there.&nbsp; </p><p><br /></p><p>The trouble with weighing (I discovered through trial and error) is that the difference between clads and 40% is just too close to call.&nbsp; I&#039;ve had many rolls with a 40% in them that weighed LESS than some all-clad rolls (but <i>usually</i>, the rolls with 40% weigh slightly more).&nbsp; The average for clad rolls on my scale is around 225.5g.&nbsp; I had the exact number (to a hundredth of a gram) plus standard deviation, yada, yada, yada... thinking that I could just weigh and skip, weigh and skip.&nbsp; But in my &#039;research&#039; I started discovering those pesky 40% Kennedys that not only fell within a standard deviation, but were actually BELOW the mean.&nbsp; Blew my whole theory.&nbsp; Back to the drawing board...</p><p><br /></p><p>I was hoping there was a way to use a metal detector, but when I asked on those forums, they said that wouldn&#039;t work either.&nbsp; I guess the bottom line is that if it was that easy, someone way smarter than me would have figured it out a long time ago.&nbsp; Shucks...[/QUOTE]</p><p><br /></p>
