'Follis' of the emperor Diocletian
From a hoard found at Preshaw Park, Beauworth, Hampshire
Around the year AD294 there was a general coinage reform, which saw the first issue of a large bronze coin known as a 'follis'. Unfortunately it was given a value far above its true worth for it contained only 5% silver and was issued with a silvery coating. Soon after AD300 the standard of the coinage began to fall and a long decline set in. 'Folles' were struck at a variety of mints - London, Trier and later Arles and Lyon in southern France. Each mint marked its products with a characteristic mint-mark, for example, PTR is the mark for Trier: P(rima officina) - denoting the division of the mint - and TR(ier).
