What money system does Turkey use?
Turkey uses the Lira. It's a decimal system, with 100 Kurus per 1 Lira. The New Turkish Lira came into effect on January 01, 2005. Exchange rate example, on October 06, 2007:
1 Turkish Lira = 0.83724 U.S. Dollars
The use of money increases economic efficiency because without it, we would be a barter system. In a barter system, if I want potatoes, and have oranges to trade, the person with the potatoes has to want oranges to be willing to trade with me. With the use of money, I can give him a known amount of value in money, which he can buy what he wants to with.
