troy weight
I have been investing (as my finances allow in silver and gold. I've read
that precious metals are weighed in troy weight. So when someone has a 1 lb. silver bar to sell, thats a troy lb, isn't it? Some bars are just marked 10.20 oz, so thats troy ounces? Do they ever go by the avoirdupois(sp) weight? I'm assuming all the spot silver/gold prices are measured in troy ounces? Thanks for the help. Barbara |

Silver and gold are also sold in grams and kilograms. So when someone has a 1 lb. silver bar to sell, thats a troy lb, isn't it? The troy pound (12 troy ounces) has not been in normal use since the 19th century, but if someone does specify a pound of precious metal it will be a troy pound. Note that a pound troy is less than a pound avoirdupois even though an ounce troy is larger than an ounce avoirdupois. Avoirdupois pound = 16 avoirdupois ounces Troy pound = 12 troy ounces Avoirdupois Pound 7000 grains 453.59 grams Troy Pound 5760 grains 373.24 grams Troy Ounce 480 grains 31.1 grams Avoirdupois Ounce 437.5 grains 28.35 grams (grains are exact, gram equivalents are approximate) Some bars are just marked 10.20 oz, so thats troy ounces? Do they ever go by the avoirdupois(sp) weight? That would be really confusing. The convention is that the weight of precious metals is either troy or metric and never avoirdupois. I'm assuming all the spot silver/gold prices are measured in troy ounces? Yes, either troy or metric. Peter. -- |

The convention is that the weight of precious metals is either troy or metric and never avoirdupois. So a "one ounce" gold or silver coin such as an American Eagle is a Troy ounce? "Coin silver" is 90% silver, 10% copper. Does a one-ounce silver coin contain one ounce of silver, or a total weight of one ounce with 90% of that being silver? If the latter (total weight one Troy ounce), an interesting coincidence is that since a Troy ounce is about 10% bigger than an av. ounce, the coin would contain about one av. ounce of silver. I'm assuming all the spot silver/gold prices are measured in troy ounces? Yes, either troy or metric. Metric (grams), not a metric ounce of some kind, right? |

Note that a pound troy is less than a pound avoirdupois even though an ounce troy is larger than an ounce avoirdupois. It was actually made illegal to use the troy pound. If someone sold precious metal by the pound I would make no assumptions, I would ask if they meant 12 troy ounces or 16 of the avoirdupois kind. Avoirdupois pound = 16 avoirdupois ounces Troy pound = 12 troy ounces Avoirdupois Pound 7000 grains 453.59 grams Troy Pound 5760 grains 373.24 grams Troy Ounce 480 grains 31.1 grams Avoirdupois Ounce 437.5 grains 28.35 grams (grains are exact, gram equivalents are approximate) Troy grains of .065grams came into use after the fall of the Western Roman Empire. The Romand and Greek grain was based on a tropical tree that the Germanic tribes did not know so they went with the more familiar barley. Some bars are just marked 10.20 oz, so thats troy ounces?
