Moidore

Moidore is an archaic term used to describe gold coins of Portuguese origin. These coins usually feature a facial value of "4000 réis", the Portuguese Coat of Arms in its obverse, and the Order of Christ Cross in its reverse, and were minted from 1677 to as late as 1910, mainly in Portugal and in Portuguese colonies like Brazil and Mozambique.

The real (meaning "royal", plural: réis or [archaic] reais) was the currency unit of Portugal from around 1430 until 1911, when the escudo was introduced after the 1910 Republican Revolution.

Since the Portuguese empire spread throughout a vast number of territories that are now part of 53 different sovereign states, the moidore was used as currency not only in those regions but also in other regions of the globe, such as Western Europe and the West Indies. The currencies of several Arabic countries are named rial or riyal after the Portuguese real.
