On 15 February 1971, known as Decimal Day, the United Kingdom and Ireland decimalized their currencies.
The last to join was Estonia on the 1st of January 2011.
Prior to 1971 the currency was very complicated. There were 12 pennies in a shilling and 20 shillings in a pound. This was not suitable for modern international commerce and especially computers.
The most important reason is concern that the value of the currency will be more easily affected by factors outside the country's control.

Poland didn't adopt euro currency yet. Poland still uses PLN (Polish New Zloty).
They didn't want to adopt to a single currency because it would withdraw their own coins and paperbill's from circulating.
THe Zloty IS the currency of Poland... and will remains so until they decide to adopt the Euro.

Jefferson designed a decimal system for weights and measures which was proposed to Congress before the metric system (The SI system) which is now used throughout the world. He also devised a decimal system for the currency based on the Spanish dollar. The former was rejected by Congress and the US stuck to the clumsy British system, adding some further problems by redefining a gallon and so on. The US is one of a handful of countries still stuck with the Imperial system though it did adopt the decimal currency in 1792.
