The coin in the images below was minted during the reign of English king Ethelred (also Aethelred or Æthelred) the Unready. His unfortunate nickname had a different meaning in his day than in Modern English.
In the Old English of his time, unræd
meant "ill-advised". It was a play on his actual name, Æthelred
which meant "nobly-advised".
The obverse text reads EÐELRED REX ANGLORV
, "Ethelred king of England".
is the Old English capital Eth, which sounds like a "th" in Modern English.
The obverse text is missing an M
at the end. After some research I found that the minting in those days was inconsistent. I found some Ethelred coins which read "ANGL", some "ANGLO", and some which read "ANGLOR".
