<p>[QUOTE=&quot;Gallienus, post: 3359759, member: 42034&quot;]Regarding coin weights, I believe that better balances would be useful.&nbsp; The cheaper $13 or so scales are not too accurate despite their ability to display many digits.&nbsp; Some years ago I compared the readings from such scales with 1st specifications on mint state coins and then an ASTM (American Soc for Testing &amp; Materials) calibrated weight set.</p><p><br /></p><p>I found that the deviation was non-linear.&nbsp; E.g. small coins were under weighed and large coins were weighed too much.&nbsp; Consequently I bought an Ohaus analytical scale (digital) open box.&nbsp; The problem is that I think it only goes up to 200 grams.[/QUOTE]</p><p><br /></p>
