A mancus of king Æthelred II, 1003-1006.

Mancus (sometimes spelt mancosus or similar) was a term used in early medieval Europe to denote either a gold coin, a weight of gold of 4.25g (equivalent to the Islamic dinar,[1] and thus lighter than the Byzantine solidus), or a unit of account of thirty silver pence. This made it worth about a month's wages for a skilled worker, such as a craftsman or a soldier.[2] Distinguishing between these uses can be extremely difficult: the will of the Anglo-Saxon king Eadred, who died in 955, illustrates the problem well with its request that "two thousand mancuses of gold be taken and minted into mancuses" (nime man twentig hund mancusa goldes and gemynetige to mancusan).[3]

Origin and development[edit]

The origin of the word mancus has long been a cause of debate. One suggested interpretation linked it to the Latin adjective mancus, meaning 'defective', which was thought to be a reference to the poor quality of gold coinage circulating in eighth-century Italy. However, it has become clear that the earliest references to payments in mancuses, which occur in north-eastern Italy in the 770s, specifically refer to Islamic gold dinars.[citation needed] Consequently, a second theory has appeared: that mancus derives from the Arabic word منقوش manqūsh (from the triliteral verbal root n-q-sh 'to sculpt, engrave, inscribe'), which was often employed in a numismatic context to mean 'struck'.

A mancus, or gold dinar of the English king Offa of Mercia (757–796), a copy of the dinars of the Abbasid Caliphate (774). It combines the Latin legend OFFA REX with Arabic legends. The date of A.H. 157 (773-774 AD) is readable.[4] British Museum.

After its first appearance in the 770s, use of the term mancus quickly spread across northern and central Italy, and leapfrogged over Gaul to reach England by the 780s. A letter written in 798 to King Coenwulf of the Mercians by Pope Leo III mentions a promise made in 786 by King Offa to send 365 mancuses to Rome every year. Use of the term mancus was at a peak between the ninth and eleventh centuries, and was only restricted to very specific locations and contexts thereafter.

The number of actual gold coins circulating in the west that would have been termed mancuses is difficult to calculate. Because of their high value such coins were less likely than other pieces to be lost, whilst the rarity of gold and its close relationship to bullion meant that coins were often melted down for re-use. Indeed, many gold coins minted in the west between the eighth and thirteenth centuries were struck in small numbers with a specific purpose in mind, and probably did not circulate commercially in quite the same way as silver coins. In many cases they had strong associations with specific issuing authorities such as a king (e.g., Coenwulf of Mercia), emperor (like Louis the Pious) or archbishop (e.g., Wigmund of York). On the other hand, they might not reference any king at all, and may relate to the issuing city (e.g., Chartres) or moneyer (like Pendred and Ciolhard at London under Offa). Some gold pieces were simply struck from regular silver dies. In addition to these gold pieces with meaningful inscriptions issued in the west, there circulated some genuine Arabic dinars and imitations of them. Curiously, several of these imitative dinars—including the famous example bearing the name of Offa of Mercia—are based on originals struck in the year 157 AH (773 or 774 AD). The precise significance of this remains uncertain: it may be that careful copies of a coin of this year circulated widely, or that particularly many dinars of this year entered the west for some reason.

For all that the surviving western specimens of early medieval gold coins must represent only a tiny proportion of the original stock, it must be borne in mind that before the thirteenth century gold coins were extremely rare in western Europe: in England, for instance, only eight native gold pieces with meaningful legends are known from c. 650 to 1066, which can be complemented by finds from the same period of half a dozen Arabic gold and perhaps ten Carolingian gold pieces or imitations of them. Substantial and regular production of gold coinage only resumed in the thirteenth century.
