![]() For example, Estonia released a platinum coin in 2008 to honor its 90th anniversary, and Tonga issued 400 platinum coins in 1967 for the coronation of Taufa'ahau Tupou IV. Many commemorative coins were dedicated to a significant event or anniversary and issued only once. For example, the Platinum Panda was produced from 1987 to 2005, and the American Platinum Eagle from 1997 to 2008. In addition to similarities in design, these coins are combined in the series because they are issued annually for a period of time. These coins are considered serial because the design of the reverse and obverse is the same or similar for all the coins of a given year. Several other countries have issued platinum coins, but only as bullion coins. The minting of a trillion-dollar platinum coin was proposed as a solution to the 2023 United States debt-ceiling crisis. The most notable examples are the Platinum cat, and Platinum Noble by the Isle of Man, Canadian Platinum Maple Leaf, Chinese Platinum Panda and Australian Platinum Koala. Since 1983, other countries have begun regular minting of platinum coins. The practice of regularly issuing platinum coins has continued in modern Russia, and since 1992 the Central Bank of Russia has released 16 sets of platinum coins. Between 19, in preparation for the 1980 Summer Olympics, the Soviet Union produced five commemorative coin sets, and since 1988 commemorative platinum coins were issued every year. The minting of platinum coins resumed only after 130 years. However, merchants valued platinum coins because it did not melt in fires like gold or silver. These coins proved to be impractical: platinum resembles many less expensive metals, and, unlike the more malleable and ductile silver and gold, it is very difficult to work. The only case when platinum coins were used as a regular national currency was in Russia, where coins were circulated between 18. This coin is also interesting because it features the portrait of the already deceased monarch George III (1738–1820). Like all test coins, the platinum farthing has a high historic and numismatic value. The coin bears the year of 1825, but was likely printed at a later date. ![]() Coins minted using dies from two different coins are called mules. No dies were manufactured for these experiments, so expired dies of the corresponding coins were used instead. The 1812 Pattern 9 Pence Bank Token (S3773A) was used for the obverse and the farthing of 1825 for the reverse parts of this coin. One of these coins has the same diameter as a farthing and a weak relief owing to the high hardness of platinum. In the late 1820s, the British Royal Mint produced several trial coins as part of experiments on the use of platinum in coins. George III had died in 1820 and had been succeeded by his son (George IV) whose farthing reverse design is shown (right). ![]() The obverse is the 1812 Pattern 9 Pence Bank Token (S3773A), and reverse is the farthing of 1825. In 1814, the United States struck a pattern half dollar in platinum.Įxperimental mule sample manufactured in the United Kingdom. ![]() Also in Spain, in the mid-19th century, counterfeiters began producing British Sovereigns out of a gold-plated alloy of platinum and copper, relying on a similar specific weight of platinum and gold. Later, the practice of adding platinum to gold as a ligature was adopted by the authorities in Spain in order to lower the gold content of coins. The platinum confiscated from counterfeiters was likely thrown into the sea, in accordance with the royal decree of 1735, however this is not confirmed, and it may be that only a few kilos were ever thrown into rivers. After the discovery that platinum alloys with gold, counterfeiters began to add it to gold coins. The then-cheap platinum was used for various kinds of frauds, such as substituting it for the more expensive silver. Following the discovery of platinum in gold rocks, the Spaniards were unable to use it for a long time because they had no technology for processing this metal. Platinum was first used for minting coins in Spanish-colonized America. The major platinum bullion coins include the American Platinum Eagle, the Canadian Platinum Maple Leaf, the Australian Platinum Koala, the Isle of Man Noble, the Chinese Platinum Panda, the Austrian Vienna Philharmonic and several series by the Soviet Union and later by the Russian Federation. ![]() Several commemorative coin sets have been issued starting from 1978 and became popular among coin collectors. As a form of currency, these coins proved to be impractical: platinum resembles many less expensive metals, and, unlike the more malleable and ductile silver and gold, it is very difficult to work. The issues of legitimate platinum coins were initiated by Spain in Spanish-colonized America in the 18th century and continued by the Russian Empire in the 19th century.
