Palladium and platinum are precious metals of the platinum group with a wide number of industrial applications in addition to bullion and coin usages.
Palladium is a steel-white metal, does not tarnish in air, and is the least dense and lowest melting of the platinum group of metals. However, its melting point is still above that of the more commonly used coinage metals. Palladium is highly lustrous, and can exhibit a bit of bluishness, especially noticeable in its industrial application in halogen lights. When palladium is annealed, it is soft and ductile, and cold working greatly increases its strength and hardness. Like gold and silver, this rare precious metal is minted into bullion for investment purposes, and can also be used as the basis for custom coins. This metal comes from refiner Johnson Matthey in strip form ready for blanking by Northwest Territorial Mint. For extensive information about palladium metal, visit this palladium web site.
Platinum, the most common metal of the platinum group, has similar characteristics as palladium, and is also traded in bullion form. Its demand in industrial applications has soared in the last couple decades for use in catalytic converters and other emissions control purposes. Since the early 1990s, platinum remains the preferred metal among various celebrities. It is regarded as the symbol of beauty and timelessness, the ultimate in elegance. Coins minted from this metal have a white-silver appearance.
Other metals can be used for coinage as well, but their use is more rare. Northwest Territorial Mint has minted coins in niobium and in zirconium in which the customer, the Wah Chang Company, supplied the difficult to obtain source metal.
Police Coins is a part of Northwest Territorial Mint, one of the Country’s largest and most respected minters of fine custom coins and medallions.
