Numismaticsis the study or collection ofcurrency,including coins, tokens, paper money, medals and related objects.

Specialists, known asnumismatists,are often characterized as students or collectors ofcoins,but the discipline also includes the broader study ofmoneyand other means ofpaymentused to resolvedebtsand exchangegoods.

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 circulatingcurrency(e.g.,cigarettesorinstant noodlesin prison). As an example, theKyrgyz peopleusedhorsesas the principal currency unit, and gave small change inlambskins;the lambskins may be suitable for numismatic study, but the horses are not.[dubiousdiscuss]Many objects have been used for centuries, such ascowry shells,precious metals,cocoa beans,large stones,andgems.(Full article...)

Abullion coin(also known as aspecie) is acoinstruck from highly refinedprecious metal(bullion) and kept as astore of valueor an investment rather than used in day-to-day commerce. A bullion coin is distinguished by its weight (or mass) andfinenesson the coin. Unlike rounds, bullion coins are minted by government mints and have alegal tenderface value. Bullion coins can have fineness ranging from 91.9% (22 karat) to 99.99% purity (24 karat).

For theVATexemption purposes theUnited Kingdomdefines investment coins more specifically as coins that have been minted after 1800, have a purity of not less than 900thousandthsand are, or have been,legal tenderin their country of origin. UnderUnited Stateslaw, "coins" that fail the last of these requirements are not coins at all, and must be advertised as "rounds" instead. (Full article...)
