Technically, bullion coins are not "rare" coins because their values are determined principally by their gold or silver bullion content, rather than by rarity or condition. The best known bullion coins are the U.S. American Eagle, the Canadian Maple Leaf, and the South African Krugerrand. These coins are bought and sold worldwide through banks, brokerage firms, coin dealers, and precious metal dealers, who offer competing prices for the coins. Bullion coin prices change daily depending on the varying prices for gold and silver in the world markets. Fraudulent sellers of bullion coins often overprice their coins, or mislead consumers about the coins bullion content. When purchasing bullion coins, call several reputable dealers or brokerage firms to compare prices and be sure to ask about any additional transaction or delivery costs. Fraudulent sellers also mislead consumers into buying "coins" that are not really coins at all. Make sure the bullion coins you purchase are not imitation medals created by fraudulent "mints." Some private mints issue bullion pieces with the same design as coins from the U. S. Mint, but in different sizes. To make sure you know what you are buying, your best protection is to study the bullion market before you buy, and to choose your dealer carefully.
