<p>[QUOTE="GDJMSP, post: 1800815, member: 112"]The problem with trying to use coins as a calibration weight is that their weight does vary. Modern mint tolerances are not as tight as they used to be. As a rule of thumb about a 1% tolerance used to be the standard. But I would think even that would be enough to screw up a calibration when you are talking 50 grams.</p><p><br /></p><p>Following Jim's advice would probably be a pretty good idea.
