What is a Real? The 14th-Century Roots of a Royal Coin

Illustrated Specimen: 5 Réis, Azores (1901)

The specimen in the photo: 5 réis, 1901 (Azores, Portuguese administration)

Obverse: In the center, the denomination is indicated by the numeral 5. The value of the coin is displayed exclusively in a numerical format — without specifying the currency name. Around the edge is the inscription: CARLOS I REI DE PORTUGAL (Carlos I — King of Portugal). Carlos I ruled from 1889 until his assassination in 1908, becoming the first Portuguese monarch to die a violent death after King Sebastian in 1578.

Reverse: Depicts the small royal coat of arms of Portugal, placed on a decorative shield topped with a crown.

Like the centavo, this coin is characteristic mostly of Spanish-speaking and Portuguese-speaking countries (Spain, Portugal, and their colonial possessions).

The real coin was issued from the 14th century by a number of states:

• SPAIN, ARGENTINA, BOLIVIA, CHILE, COLOMBIA, COSTA RICA, DOMINICAN REPUBLIC, ECUADOR, GUATEMALA, HONDURAS, MEXICO, NICARAGUA, PARAGUAY, PERU, PHILIPPINES, VENEZUELA...
• PORTUGAL, ANGOLA, AZORES, BRAZIL, CAPE VERDE (banknotes only), GUINEA-BISSAU (banknotes only), MADEIRA, MOZAMBIQUE, SÃO TOMÉ AND PRÍNCIPE...

Origin of the name: The word "real" comes from the Latin realis, meaning "royal" or "belonging to the king." This name directly indicated that the coin was issued under supreme monarchical authority. In Spanish and Portuguese, a thousand réis was traditionally denoted by the term "milréis", where "mil" means a thousand. In Portugal, the name milréis became even more popular in everyday use than the real itself.

History and Global Impact of the Real Coin

The real is one of the most influential coin denominations of the Iberian world. Appearing in medieval Spain in the mid-14th century (during the Crown of Castile), it was soon adopted by Portugal. From there, this currency spread through vast colonial empires in Europe, the Americas, Africa, and Asia.

The Spanish Real and International Trade

Spanish reales became the backbone of international trade between the 16th and 19th centuries. The famous silver 8-real coin (known as the "Spanish dollar" or "piece of eight") circulated on all continents and became one of the first global currencies in history. During 1850-1864, the real acted as the main currency of Spain (previously it was 1/16 of an escudo). In 1864, it was replaced by the new escudo. In numerous Spanish colonies in Asia and the Americas, the real was used as a fractional coin for the peso until the transition to the decimal system at the end of the 19th century. Many modern currencies, including the US dollar, were shaped under the influence of the monetary system based on the real.

The Portuguese System and Colonies

The Portuguese real was minted for about half a millennium — until 1911, when, after the overthrow of the monarchy and the establishment of a republican form of government, it was replaced by the Portuguese escudo. Modern Portuguese autonomous regions also used their own real coins in circulation: the Azores until 1901, and Madeira until 1852. Portugal's colonies on the African continent (Angola, Mozambique, São Tomé and Príncipe) actively used the real in their monetary circulation until the mass introduction of colonial escudos in 1914.

The Modern Brazilian Real

In Brazil, the historical real (plural — réis) was the national currency during 1690-1942. The historical name was revived in 1994 for the new Brazilian currency. Today, the modern Brazilian real is divided into 100 centavos and is the only major currency in the world that still bears this historical name.
