<p>[QUOTE="kaparthy, post: 3541419, member: 57463"]For myself, I accept that many of these private issues are actually heavier than one ounce by some little bit. The reasons are that cheaters will cheat on the weight, and that the honest sellers will err on the side of caution. That second is especially true of small companies. I expect Silvertowne and others at that level to be exact, just by quality control and years of experience.</p><p><br /></p><p>Also, as an aside, when I worked at a college and had access to the labs, I weighed many coins, mostly ancients. At some level, you get the plus/minus of tolerance. The scales were used by students, of course, so if they ever were calibrated, they lost that soon enough. But that aside, having also used professional equipment, again, at some level, the same person (me) weighing the same coin on the same instrument will get different results after a few decimal places.[/QUOTE]</p><p><br /></p>
