when and how was the world currency named?

Question

who came up the pound, dollar naira yen etc for the world currencies

Answer 1

I can only answer parts of your question.
Some currency names are derived from the original Latin names for coins. Some examples are as follows:
Dinar (Serbia, Iraq) : Derived from Latin "Dinara", a copper coin
Lira (Italy, Turkey, Cyprus) or Livre (Lebanon): Derived from Latin "Libra", a gold coin

Other counties name currency after national heroes. The Tajikistan currency, the Somoni, is named after the father of the Tajik nation, Ismail Samani (or spelled Ismoil Somoni)

As for the Euro: The possible recommendations for the name, of course, were depending on the national identity of the states. In France they would have liked to call it Eurofranc, the Germans recommended Euromarc and the English idea was to name it Europound. The Dutch proposal finally ended the demur: „Gentleman, what if we used the first four letters”.

In other words, the origin of currency names just depends on what a country chooses to call it, each has a different reason, and reasons can vary greatly.

Answer 2

Go back not so long in time with your wallet, and they'd laugh and ridicule you for saying your paper money was "money".

Quick outline - paper money came about from receipts that goldbrokers, who kept their customer's gold safe in their vaults, issued to the customer as proof/validation of holding.

Time came that a few people exchanged these receipts for other valuable items, and the receipt could be used to recover the gold.

Governments caught on to it, and began issuing their own receipts/paper, with the paper backed up by the value of exchange of gold of that value by promise of the Government.
