History
The 8th-century English king Offa of Mercia minted imitations of Abbasid dinars struck in 774 by Caliph al-Mansur with "Offa Rex" centred on the reverse. The moneyer likely had no understanding of Arabic as the Arabic text contains many errors. Such coins may have been produced for trade with Islamic Spain. These coins are called a Mancus, which is also derived from the Arabic language.
