The first minted coin, about 2600 years ago, allowed to buy 10 goats. And the currency was not always circular: there was once square coins, star-shaped, with holes, porcelain and wooden coins. The Chinese, for example, have used pressed tea bricks as currency. HEADS OR TAILS tells the history of the currency throughout the ages, in Portugal and worldwide.
