Испанский реаль: история валюты с XIV по XIX век.

Historical currency of Spain, used from the mid 14th century to 1868

The real (English: /ɹeɪˈɑl/ Spanish: /reˈal/) (meaning: "royal", plural: reales) was a unit of currency in Spain for several centuries after the mid 14th century. It underwent several changes in value relative to other units throughout its lifetime until it was replaced by the peseta in 1868. The most common denomination for the currency was the silver eight real Spanish dollar (Real de a 8) or peso which was used throughout Europe, America and Asia during the height of the Spanish Empire.

The first real was introduced by King Pedro I of Castile in the mid 14th century, with 66 minted from a Castilian mark of silver (230.0465 grams) in a fineness of 134/144 (0.9306), and valued of 3 maravedíes. It circulated beside various other silver coins until a 1497 ordinance eliminated all other coins and retained the real (now minted 67 to a mark of silver, 0.9306 fine, fine silver of 3.195 grams) subdivided into 34 maravedíes. The silver real was minted in , 1 , 2 , 4 and 8 real denominations. After the discovery of silver in Mexico, Peru and Bolivia in the 16th century, the 8 real coin (referred to since then as a dollar, a peso or a piece of eight) became an internationally recognized trade coin in Europe, Asia and North America. These reales were supplemented by the gold escudo, minted 68 to a mark of 11/12 fine gold (3.101 g fine gold), and valued at 15–16 silver reales or approximately two dollars. This real, worth 1/8 dollar, was retained in Latin America until the 19th century but was altered considerably in peninsular Spain beginning in the 17th century. This Spanish colonial real was subsequently referred to as moneda nacional ("national money") and underwent two more changes:
1728: 68 reales (or 8 1/2 dollars) minted to a mark, 11/12 or 0.9167 fine (3.101 g fine silver)
1772: 8 1/2 dollars minted to a mark, 130/144 or 0.9028 fine (3.054 g fine silver)

The loss of American possessions in the first third of the 19th century cut off the inflow of precious metals into Spain and resulted in the gradual use of French coinage in local circulation. These subsequent changes to the Spanish currency system were never carried out in full:
The first decimal currency of 1850, with the real de vellón worth 1/20 dollar, 10 décimas or 100 céntimos, and with maravedíes discontinued. The second decimal currency of 1864, with a new silver escudo worth dollar, 10 reales de vellón or 100 céntimos de escudo (not equivalent to the gold escudo). The real was only retired completely with the introduction in 1868 of the Spanish peseta, at par with the French franc, and at the rate of 1 dollar = 20 reales = 5 pesetas. Consequently, the term real lived on, meaning a quarter of a peseta (25 céntimos de peseta).

Coins were minted in both Spain and Latin America from the 16th to 19th centuries in silver , 1, 2, 4 and 8 reales nacionales and in gold , 1, 2, 4 and 8 escudos. The silver 8 real coin was known as the Spanish dollar (as the coin was minted to the specifications of the thaler of the Holy Roman Empire and Habsburg monarchy), peso, duro or the famous piece of eight. Spanish dollars minted between 1732 and 1773 are also often referred to as columnarios. The portrait variety from 1772 and later are typically referred to as Spanish dollars or pillar dollars. Coins were minted in Spain in copper 1, 2, 4 and 8 maravedíes, in silver coins equivalent to 1, 2, 4, 10 and 20 reales de vellón since 1737, and in gold coins equivalent to , 1, 2, 4 and 8 escudos. New coins introduced after the 1850 decimalization include copper 5, 10 and 25 céntimos de real as well as a new gold 100 real (5 dollar) coin.
