What are California fractional gold coins?
California fractional gold coins are tokens struck in California to make up for the lack of US small denomination coins in the western US. During the early gold rushes, there was no nearby US mint in the west, and there was an abundance of gold. So people used the US gold standard price ($20.67 per troy ounce, since the US dollar was on a gold standard) and made coins with the required amount of gold to make up for small change. These coins are today very collectible, however, fakes abound and there is little information about them online.
What is the difference between 14 and 18 carats?
The carat or karat (US) refers to the purity of gold. 24 kt is 100% gold, but is too soft to be made into jewelry that will last. 18 kt is (18/24) or 75% gold and 25% other metals. 14 karat is 14/24 (about 58 %) gold, and about 42 % other metals. Having the other metals, gives gold jewelry its durability as well as color, depending on what is chosen for the other metals. Carats for diamonds refer to the weight of the diamond. 1 ct is 200 milligrams or 1/142 ounce.
Which weighs more a hundred pounds of gold or a hundred pounds of feathers?
One user said:While on the face of it a pound of feathers would seem to weigh the same as a pound of gold, this overlooks the fact that gold is universally weighed using a different definition of 'pound' than that used for most other materials.Precious metals such as gold are measured in troy weight. A troy pound is 12 troy ounces, and each troy ounce is 480 grains, making a total of 5760 grains to the pound of gold.Most materials use pounds and ounces from the avoirdupois system, and such a standard pound is made up of 16 ounces, where each ounce is 437.5 grains, making a total of 7000 grains to the pound of feathers.All this means that a "pound" of feathers (or bricks, or lead) is heavier than a "pound" of gold.
