Aethelred II achieved the rather unfortunate moniker of Aethelred 'The Unready' after a mistranslation of Old English 'unręd' as 'unready'. A better translation might be 'ill-advised' or 'poorly-counseled'. He had not even reached puberty when the previous King was murdered (his half-brother Edward), and as such he was definitely not ready for the task of ruling a kingdom. His short reign consisted mostly of paying Danegeld to the Vikings, and tired this, he ordered all Danish men in England to be massacred on 'St. Bryce day' (November 13th, 1002 AD). In 1003 the Viking king Sweyn Forkbeard of Denmark-Norway invaded England in retaliation, and thus Aethelred's rule came to an abrupt end.
These silver pennies were the main currency of the time, used for most marketplace transactions of everyday life. The obverse inscription reads '+ AEDELRED REX - ANGLO(X)', with the 'NG' of 'ANGLO' sometimes written together in a ligature, making it look like a single letter. The reverse inscription on requester Timmy's coin most closely fits 'LEO - FRIC - MTO - CENT', with 'Leofric' being the name of the moneyer, and 'CENT' being an abbreviation of Canterbury, the city where the coin was minted. Other reverse inscriptions are possible.
The coin in our main picture (upper left) is a superb specimen from Spink in London. It sold for 1700 GBP (about $2500 US dollars) during a 2015 auction.
Very approximately, catalog values go like this:
worn: $500 US dollars approximate catalog value
average circulated: $1000
well preserved: $2500
To give an idea of the variability of pricing for a coin like this, the (A) coin to the right sold at auction for $200. It is bent and this detracts from value. But the (B) coin also has damage. It sold for $1000 at auction. Go figure! The (C) coin sells as a novelty for a few dollars. It is a fake.
