Where did this go?
As seen in this image, Islamic gold coins from the eleventh and twelfth centuries have been found throughout England. It is possible that crusaders brought these coins back with them, knowing them to be of significant value. Another more likely theory is that these coins made their way to England through commerce as Islamic states were known to engage in trade with European nations across the Mediterranean. In fact, "there now appears to be solid evidence for English merchants engaging in a significant degree of commerce with Spain in the eleventh and twelfth centuries" (Green). The number of Islamic gold coins in England during this time is believed to be relatively large and further highlights their value.
Moreover, across Europe, coins with Islamic inscriptions were inherently worth more due to the prestige of gold dinars. As a result, gold dinars were often imitated and reproduced and became "the dominant coinage in the Mediterranean" (British library). This specific coin is an imitation of an Abbasid dinar, however, it is easily identified as a copy through errors in its Arabic inscription. Even so, the reputation of Islamic gold coins was sufficient for it to retain value. This coin was first found in Rome and believed to have been a gift from King Offa of England. Therefore, it is reasonable to assume some imitations were minted in England and then used as gifts of diplomacy.
