Penny of Eadwald (796-798) of East Anglia, damaged with around one third of the coin missing.
In the moneyer's name the form of the letter U resembles a Roman N with a high bar, and the form of the letter D resembles a reversed 6. Both forms are illustrated in BMC and redrawn on page 252 of North's English Hammered Coinage.
