Gold coins are made mostly or entirely of gold. Gold has been for coins practically since the invention of coinage, originally because of gold's intrinsic value. In modern times, most gold coins are for collectors, or as bullion coins. Gold Bullion Coins whose nominal value is irrelevant and which serve primarily as a method of investing in gold. Gold has been as money for many reasons. It is fungible, meaning that it trades easily, with a low spread between the prices to buy and sell. Gold Coins are easily transportable, as it has a high value to weight ratio, compared to other commodities, such as silver. Gold can be into smaller units, without destroying its value; it melts into ingots, and re-coined. The density of gold is higher than most other metals, making it difficult to pass counterfeits. Gold is extremely un-reactive. The scarcity of gold stabilizes its value. Precious metals in bulk form are bullion, and trade on commodity markets. Bullion metals cast into ingots, or minted into coins. The defining attribute of bullion is that it is valued by its mass and purity rather than by a face value as money. While obsolete gold coins collected for their numismatic value, gold bullion coins today derive their value from the metal content and viewed by some investors as a "hedge" against inflation or a store of value. Many nations mint bullion coins. The European Commission publishes annually a list of gold coins, which are as investment gold coins in all EU Member States. The list has legal force and supplements the law. South Africa introduced the Krugerrand in 1967 to cater to this market; this was the reason for its convenient and memorable gold content — exactly one troy ounce. It was the first modern, low premium gold bullion coin. Bullion gold coins are also in fractions of an ounce – typically half ounce, quarter ounce, and one-tenth ounce. Bullion coins sometimes carry a face value as legal tender, the face value is on the coin, and in order to bestow legal tender status on a coin, which generally makes it easier to import or export across national borders, as well as subject to counterfeiting. However, their real value is as dictated by their troy weight, the current market price of the precious metal contained, and the prevailing premium that market wishes to pay for those particular bullion coins. The face value is always significantly less than the bullion value of the coin. Legal tender bullion coins are a separate entity to bullion gold. One enjoys legal tender status; the latter is merely a raw commodity. Coins are usually made of an alloy as other metals are into the coin to make it more durable. Fineness is the actual gold content in a coin or bar and expressed in grams or troy ounces. Karat weight is a unit of fineness for gold equal to 1/24 part of pure gold in an alloy. Pure gold is 1000 fine. Below is a karat weight to fineness conversion chart. There is a correlation between karats and fineness: 24 karats = 1000 fine, 23 karats = 958.3 fine, 22 karats = 916.6 fine, 21 karats = 875.0 fine, 20 karats = 833.3 fine, 18 karats = 750.0 fine, 16 karats = 666.7 fine, 14 karats = 583.3 fine, 10 karats = 416.6 fine.

American Silver Eagle

The American Silver Eagle is the official silver bullion coin of the United States of America. The United States Mint first released it in November 1986. It struck only in the one-troy ounce size, which has a face value of 1 dollar and guaranteed to contain one troy ounce of 99.9% pure silver. The United States Mint certifies its content, purity, and weight. Silver Eagle bullion coins, along with American Gold Eagle bullion coins are viable investment alternatives to the gold and silver bullion coins produced by other countries. To ensure wide distribution of the coins, the United States Mint awarded a contract to Grey Advertising to assist in marketing and publicizing the coins domestically and internationally. The design on the coin's obverse taken from the "Walking Liberty" design by Adolph A. Weinman, which originally had been used on the Walking Liberty Half Dollar coin of the United States from 1916 to 1947. As this iconic design had been a public favorite—and indeed one of the most beloved designs of any United States coinage of modern times, silver or otherwise—it revived for the Silver Eagle decades later. The obverse inscribed with the year of minting or issuance, the word LIBERTY, and the phrase IN GOD WE TRUST. The reverse is by John Mercanti and portrays a heraldic eagle behind a shield; the eagle grasps an olive branch in its right talon and arrows in its left talon, echoing the Great Seal of the United States; above the eagle are thirteen five-pointed stars representing the Thirteen Colonies. The reverse inscribed with the phrases UNITED STATES OF AMERICA, 1 OZ. FINE SILVER ONE DOLLAR, and E PLURIBUS UNUM as well as the applicable mintmark. Like the American Gold Eagle and American Platinum Eagle bullion coins, the United States Mint does not sell Silver Eagle bullion coins directly to the public. In order to provide "effective and efficient distribution, which maximizes the availability of the coins in retail markets as well as major investment markets" the Mint utilizes a network of authorized purchasers to distribute the coins. The coins sold in bulk at a premium over the spot price of silver. The coins sold to banks, brokerage companies, coin dealers, precious metal firms, and wholesalers that meet the following requirements. Be an experienced and established market maker in silver bullion coins. Provide a liquid two-way market for the coins. Be audited annually by an internationally accepted accounting firm. Have an established broad base of retail customers to which to distribute the coins. Have a tangible net worth of $5 million. Authorized purchasers must order a minimum of 25,000 coins, which they sell to secondary retailers that sell them, in turn, to the public.
