Simply, the coinage, itself, is a masterpiece of art and it also indicates the nation’s culture and history. HISTORY OF BANK NOTES

After year 600 Chinese as the first nation introduced during yhe T'ang Dynasty paper money in little amount. China experienced over 700 years of early paper money, spanning from the 7th throug the 15th century. During Ming Dynasty the Chinese placed the emperor's seal and signature of the treasures on a crude paper made from mullberry bark. This was the first attempt in history to avoid the falsificating paper money. Over whole period from 7th to 15th century, paper notes grew in production to the point that their value rapidly depreciated and inflation soared. Then beginning in 1455, the use of paper money in China disappeared for 700 years. People in Mongolia were the second who began to use paper money in eleventh century. Paper notes appeared much later in Europe, in 1661 in Stockholm, Sweden.
150 years after notes spread to Europe, people needed to number them. This was done at first by stamps. In 1809 Englishman Joseph Bramah invented a machine for numbering of notes and offered it to National Bank of England.

Watermark

The 1st watermark came into existence by chance in Fabiano's paper factory in Italy in about 1260. There was a little wire projecting from a die for pressing the water out of paper. On the place, where the wire was pressed, the paper was thiner and more diaphausus against the light. The manufactures realized that they can make different shapes of wire pressed to the paper. The first patterns (usually of cross shape) were used as quality mark of paper factories. Later, watermark was used as very important item to avoid falsification of bank notes.

Destroying of bank notes

Coins are much more durabily than notes and so can stay longer in circulation. The notes of lower value go from hand to hand very quickly so their lifespan is not longer than few months. Every country has to destroy their notes. This is usually done by two ways: burning them by the temperature of 2000 degrees of Celsius, cutting them into little squares of 1x1 mm.
In august 1963 by Great train robbery a group of thiefs stole notes commited to destroying in value of 2.6 mil pounds. In fact they stole notes which weren't existing anymore.
In 1988 Australia brought out new ten-dollar note made from plastic material which is impossible to damage in everyday use.
