In Novemember of 1983, the Isle of Man, a British Crown dependency, released the one ounce Noble - the world's first legal tender platinum bullion coin. Following the success of the Noble, other mints began to issue platinum bullion coins. In the second half of 1988, the Australian Koala and the Canadian Maple Leaf platinum coins were introduced to great success. As a result, investment demand for platinum, especially in the form of bullion coins, has become very popular.
Collectible platinum bullion coins are rare and precious and are always welcome additions to any coin collection.
Although platinum bullion coins are legal tender with a face value, their actual value is determined by the weight of the platinum content and far exceeds the face value. Some bullion coins have numismatic value on top of the bullion value. These are known as collectible bullion coins and are usually limited in mintage and have designs that changes every year. These coins usually sell at a higher premium than the pure bullion coins. If the series is successful, the premium of the earlier coins in the series can go up substantially, sometimes even exceeding the bullion value! A popular collectible bullion coin series is the American Platinum Eagle series.
