<p>[QUOTE=&quot;desertgem, post: 1869951, member: 15199&quot;]Since digital balances round off the last digit, the more resolution you can get the better ( 0.01 better than .1), but usually at the sacrifice of total range (highest weight). For mass of sterling to send to melt, a kg @ 1 gram&nbsp; would probably be OK, as the smelter will accurately weigh it themselves. If you are trying to authenticate coins by weight,&nbsp; 50grams&nbsp; X .001 accuracy would be good.&nbsp;&nbsp; Balances with the better resolution cost more as they use better sensors, but should last a lifetime ( or until you loan it out <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" />&nbsp; Try to get one that has a calibration weight ( treat that like a coin and put in a plastic bag or such).</p><p>Jim[/QUOTE]</p><p><br /></p>
