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.[dubiousdiscuss] Many objects have been used for centuries, such as cowry shells, precious metals, cocoa beans, large stones, and gems.

A banknote or bank note – also called a bill (North American English) or simply a note – is a type of paper money that is made and distributed ("issued") by a bank of issue, payable to the bearer on demand. Banknotes were originally issued by commercial banks, which were legally required to redeem the notes for legal tender (usually gold or silver coin) when presented to the chief cashier of the originating bank. These commercial banknotes only traded at face value in the market served by the issuing bank. Commercial banknotes have primarily been replaced by national banknotes issued by central banks or monetary authorities.

By extension, the word "banknote" is sometimes used (including by collectors) to refer more generally to paper money, but in a strict sense notes that have not been issued by banks, e.g. government notes, are not banknotes.[better source needed] (Full article...)

The American Buffalo, also known as a gold buffalo, is a 24-karat bullion coin first offered for sale by the United States Mint in 2006. The coin follows the design of the Indian Head nickel and has gained its nickname from the American Bison on the reverse side of the design. This was the first time the United States government minted pure (.9999) 24-karat gold coins for the public. The coin contains one-troy ounce (31.1g) of pure gold and has a legal tender (face) value of US$50. Due to a combination of the coin's popularity and the increase in the price of gold, the coin's value has increased considerably. The initial 2006 U.S. Mint price of the proof coin was $800. In 2007 the price was $899.95, $1,410 in 2009, $2,010 in 2011, and $3,590 in 2024.

In addition to requiring a presidential dollar coin series to begin in 2007 and redesigning the cent in 2009, the Presidential $1 Coin Act of 2005 mandated the production of a one-ounce 24-karat gold bullion coin with a face value of $50 and a mintage limit of up to 300,000 coins.
