Coins or sometimes called coins (from English coin) are metals used as a means of economic transactions and are usually published by the government.
Usually coins are round but this is not always the case. A coin usually has two sides: a side that displays the value of money being represented and the opposite side which is usually in the form. Coins from royal countries usually feature a picture of the head of state on this last side.
The coin has a history of thousands of years although it is not known exactly where and when the first coin was made. But it is believed there are three different traditions:
1.The ancient Chinese
2.Indian India
about money, of course face if there will always be a new model printed by the state.
Usually if there is a new version, people can not wait to have it.
Old model money was little by little began to be forgotten, some even no longer valid
Some people trade it for new, but not a few who still keep it.
The reason is not just for the collection alone, but the belief that if one day the money will be more valuable than its value.
And that belief turns out to be true.
Some old money, especially in the 90s, now the price skyrocketed.
