 According to the thirteenth-century chronicler Roger of Wendover, Eardwulf was replaced by King Ælfwald II, about whom nothing else is known from the written sources, although coins issued in his reign have survived.As the case of Ælfwald shows, while the written sources for later Northumbria are few and often written down centuries after the events they describe, archaeological evidence from coinage is independent of the surviving annals.Anglo-Saxon coins usually named the king on whose orders they were issued and sometimes named the mint where they were struck—Northumbrian coinage names York as the place of issue—and the moneyer who produced them.
