<p>[QUOTE=&quot;BC Chicago, post: 2457194, member: 80070&quot;]I have weighed over 100 Morgan silver dollars on a US Balance electronic sscae, their condition ranging from AG-3 to MS-70. The mint standard is 26.73 gm. The published tolerance is .097 gm but this is for the mint&#039;s tolerance only, without reference to scale error or coin wear. I found that the most heavily worn coins (AG) weighed on average 25.5 gm... thus showing slightly less than 5% weight loss. However, loss as a function of wear (rating) was NOT&nbsp; linear. From high-side EF to MS showed very little wear. Most wear in weight loss occurred from EF down to Fine / VG. Hence, the &quot;real&quot; standard often cited... +/- 1%, is reasonable for EF-MS coins. For coins showing more wear, up to 4 to 5% might be seen. But, fortunately, counterfeits almost never show that much wear.[/QUOTE]</p><p><br /></p>
