The coin revolution began in around 670 A.C. in Lydia (now Turkey) with the issue of the first coin produced in a gold and silver called "Electrum". The coin has two faces, on one side there is a figurative element (harp) and on the other side, but not always, an epigraphic element (legend). Everything stamped on the coin, or rather the type and legend are called the imprint. The title is the level of purity with which the metal is used for a determined coin. The scale of conservation and assessment is divided up as follows: uncirculated (UNC), extra fine (EF), very fine (VF), fine (F), very good (VG) and good (G). Furthermore, C is used to indicate current coins and K for common coins. Gold coins are legal tender in the country of issue, normally they are coined in different sizes, the real value depends on the gold content (which is always guaranteed) and the price is negotiated and published daily. The spread between the purchase and sale price is limited. Gold coins are as old as the history of civilized man and represent the last step of swaps . From 1970 to 1990 coins represented 14% of all new gold extracted, with more than 60,000,000 pieces in circulation. The most traded coins are: the South African Krugerrand, the Mexican 50 pesos, the United States Double Eagle or 20 dollars, the Great British pound and the Australian Nugget.
