Numismatics is the study or collection of currency, including coins, tokens, paper money, medals and related objects.

Specialists, known as numismatists, are often characterized as students or collectors of coins, but the discipline also includes the broader study of money and other means of payment used to resolve debts and exchange goods.

The earliest forms of money used by people are categorised by collectors as "odd and curious", but the use of other goods in barter exchange is excluded, even where used as a circulating currency (e.g., cigarettes or instant noodles in prison). As an example, the Kyrgyz people used horses as the principal currency unit, and gave small change in lambskins; the lambskins may be suitable for numismatic study, but the horses are not.[dubious ] Many objects have been used for centuries, such as cowry shells, precious metals, cocoa beans, large stones, and gems.

Banknotes of the Australian dollar in a wallet. In 1988, Australia was the first country to introduce polymer banknotes for circulation.

Polymer banknotes are banknotes made from a synthetic polymer such as biaxially oriented polypropylene (BOPP). Such notes incorporate many security features not available in paper banknotes, including the use of metameric inks. Polymer banknotes last significantly longer than paper notes, causing a decrease in environmental impact and a reduced cost of production and replacement. Modern polymer banknotes were first developed by the Reserve Bank of Australia (RBA), Commonwealth Scientific and Industrial Research Organisation (CSIRO) and The University of Melbourne. They were first issued as currency in Australia during 1988 (coinciding with Australia's bicentennial year); by 1996, the Australian dollar was switched completely to polymer banknotes. Romania was the first country in Europe to issue a plastic note in 1999 and became the third country after Australia and New Zealand to fully convert to polymer by 2003.

Other currencies that have been switched completely to polymer banknotes include: the Vietnamese đồng (2006) although this is only applied to banknotes with denominations above 5,000 đồng, the Brunei dollar (2006), the Nigerian Naira (2007), the Papua New Guinean kina (2008), the Canadian dollar (2013), the Maldivian rufiyaa (2017), the Mauritanian ouguiya (2017), the Nicaraguan córdoba (2017), the Vanuatu vatu (2017), the Eastern Caribbean dollar (2019), the pound sterling (2021) and the Barbadian dollar (2022). Several countries and regions have now introduced polymer banknotes into commemorative or general circulation, including: Nigeria, Cape Verde, Chile, The Gambia, Trinidad and Tobago, Vietnam, Mexico, Singapore, Malaysia, Botswana, São Tomé and Príncipe, North Macedonia, Russia, Solomon Islands, Samoa, Morocco, Albania, Sri Lanka, Hong Kong, Israel, China, Taiwan, Kuwait, Mozambique, Saudi Arabia, Isle of Man, Guatemala, Haiti, Jamaica, Libya, Mauritius, Costa Rica, Honduras, Angola, Namibia, Lebanon, the Philippines, and Egypt.

The Mercury dime is a ten-cent coin struck by the United States Mint from late 1916 to 1945. Designed by Adolph Weinman and also referred to as the Winged Liberty Head dime, it gained its common name because the obverse depiction of a young Liberty, identifiable by her winged Phrygian cap, was confused with the Roman god Mercury. Weinman is believed to have used Elsie Stevens, the wife of lawyer and poet Wallace Stevens, as a model. The coin's reverse depicts a fasces, symbolizing unity and strength, and an olive branch, signifying peace.

By 1916, the dime, quarter, and half dollar designed by Mint Chief Engraver Charles E. Barber had been struck for 25 years, and could be replaced by the Treasury, of which the Mint is a part, without Congressional authorization. Mint officials were under the misapprehension that the designs had to be changed, and held a competition among three sculptors, in which Barber, who had been in his position for 36 years, also took part. Weinman's designs for the dime and half dollar were selected. (Full article...)
