<p>[QUOTE="Kentucky, post: 1434584, member: 33176"]OK, here's the deal. Precious metals are normally weighed in Troy weights. A Troy ounce is 31.1035 grams. Cheese, feathers and other items of daily commerce are weighed in Avoisdupois weights. An Avoisdupois (Av) ounce is 28.3495 grams. We sometimes see sellers on e-bay trying to sell ounces of coins using the Av scale. This could give them an edge of about 9% (hmmm about what the CoinStar change machines charge). Just for fun, and to make matters worse, a Troy pound has only 12 Troy ounces while an Av pound has 16 Av ounces. So........an ounce of gold weighs more than an ounce of cheese, but a pound of cheese would weigh more than a pound of gold. Whatever happened to "A pint's a pound, The world around"? </p><p><br /></p><p>BTW a good list of coin weights can be found at:</p><p><a href="http://www.treasurerealm.com/coinpapers/USCoins/silvercoins.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.treasurerealm.com/coinpapers/USCoins/silvercoins.html" rel="nofollow">http://www.treasurerealm.com/coinpapers/USCoins/silvercoins.html</a>[/QUOTE]</p><p><br /></p>
