1 ounce coin - With 31.103 g platinum content, 31.119 g in weight, and 32.7 mm in diameter. The coins have no currency value. Their value, rather, is equal to their respective platinum contents. All coins consist of 0.9995 pure platinum. On the coin's obverse is Queen Elizabeth II, along with these texts: "ISLE OF MAN" and "ELIZABETH II". Here, it is clear that the currency value assigned by the government to a gold bullion coin has no meaning. Below is a list of some of the government-issued gold and silver bullion coins: 1. Australian Gold Nugget, Lunar Series I, and Lunar Series II 2. Austrian Philharmoniker 3. Canadian Maple Leaf 4. Medicine (silver compounds and silver ions have toxic effect on some viruses, fungi and bacteria, but not on humans). 10. Currency or coinage (as in silver bullion). The principal sources of silver are copper, lead, zinc and gold ores. It also occurs in the minerals chlorargyrite and argentite. Of course, silver occurs natively, too. It is also known to be the most expensive precious metal, with a price estimated to be about USD2,750 per troy ounce (USD88,415 per kilogram) as of January 2010. 3. Palladium - This element is represented by the symbol Pd. Its atomic number is 46. It is also considered one of the rarest precious metals. The fixing is done twice - once in the morning and another in the afternoon. The latter actually was introduced about 49 years after the procedure itself was introduced, as a means of providing a price when US markets are open. This gold-price fixing procedure is done by the five members of the London Gold Market Fixing Ltd. The Norilsk Nickel Mining and Metallurgical Company in northern Russia is the largest single producer of palladium in the world. Significant amounts of mineable palladium are also found in two other places: the Lac des les igneous complex in northwestern Ontario, Canada and the Stillwater igneous complex in the state of Montana in the United States.
