A silver penny of Burghred of Mercia, found in the mass grave at Repton, minted by the moneyer Dudda, probably in London. Burghred was king of Mercia from 852-874 CE. He was driven out of Mercia by the Vikings during their march from Lindsey to Repton in 874 after they sacked Tamworth. Burghred fled to Rome, where he eventually died, and was replaced by Ceowulf II who was loyal to the Vikings.

Minting coins was a way of controlling the means of exchange within a kingdom and which created a more easily administered standardized system of trade. Moreover, the coins themselves were often used as propaganda, portaying symbols and statements that gave off a desired message. The Vikings later used the minting of coins to legitimize their own rule.
