Introduction

Numismatics is the study or collection of currency, including coins, tokens, paper money and related objects. While numismatists are often characterised as students or collectors of coins, the discipline also includes the broader study of money and other payment media used to resolve debts and the exchange of goods. Early money used by people is referred to 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 in prison). 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. Many objects have been used for centuries, such as cowry shells, precious metals, cocoa beans, large stones, and gems.

Polymer banknotes were developed by the Reserve Bank of Australia and the Commonwealth Scientific and Industrial Research Organisation and were first issued as currency in Australia in 1988. These banknotes are made from the polymer biaxially-oriented polypropylene which greatly enhances durability of the banknotes. Polymer banknotes also incorporate many security features not available to paper banknotes, making counterfeiting much more difficult.

An alternative polymer of polyethylene fibres marketed as Tyvek by DuPont was developed for use as currency by the American Bank Note Company in the early 1980s. Tyvek did not perform well in trials, smudging of ink and fragility were reported problems. Only Costa Rica and Haiti issued Tyvek banknotes; additionally, English printers Bradbury Wilkinson and Company produced a version on Tyvek but marketed as Bradvek for the Isle of Man in 1983; however, they are no longer produced and have become collectors' items.

The Mercury dime is a ten-cent coin struck by the United States Mint from 1916 to 1945. Designed by Adolph Weinman and also known as the Winged Liberty dime, it gained its common name as 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.

Although the new coin's design was admired for its beauty, the Mint made modifications to it upon learning that vending machine manufacturers were having difficulties making the new dime work in their devices. The coin continued to be minted until 1945, when the Treasury ordered that a new design, featuring recently deceased president Franklin Roosevelt, take its place.
