Richard Henry, Portable Antiquities Scheme Finds Liaion Officer for Worcestershire and Warwickshire, puts the coins represented in the Bredon Hill Roman Coin Hoard into context in this series of posts.
A common theme throughout is debasement; coins, which were meant to be around 90% silver, contained barely 1%. It is interesting to see that under the reformed coinage the fact that each coin had a higher silver content was advertised. The marks PXXI at the bottom of the coin denote the mint and the silver content. It is a stark improvement, although it is still only 20 parts copper to 1 part silver (5%).
Richard works closely with Museums Worcestershire in his role for the Portable Antiquities Scheme, a goverment-funded scheme co-ordinated by the British Museum.
