Palladium coins have been minted due to an investor demand for this very rare Platinum Family metal. Palladium, like platinum, is also used in catalytic converters in automobiles. This is the only other type of metal that has the same characteristics that can be substituted for platinum for converting auto emissions toxic gasses into more harmless gasses, but platinum currently is in more demand than palladium. Palladium is also a gray color metal similar looking to nickel and platinum, but has a lower melting point and is not as dense as platinum. Palladium is often used in jewelry and in dentistry as well.
Russia is the major mining producer of platinum and palladium with South Africa in second place. Canada, the United States and Australia also mine palladium.
Canada in the past has produced palladium bullion coins:
Canadian Palladium Maple Leaf also minted in one ounce denominations, production of these coins halted in 2005, but are still available through dealers;
PAMP and Credit Suisse still produce one ounce or smaller bars (in grams) available through various coin dealers.
The bars and coins made principally for industrial and testing purposes are made by American Elements, Inc. These can also be purchased at Metallium, Inc., a distributor:
