Thomas Bushell, the lessee of the royal mines in Cardiganshire, petitioned the king for permission to set up a mint in Aberystwyth castle to save him having to send the local silver to London to be coined. Local silver was struck into half-crowns, shillings, half-shillings, groats, threepences, half-groats, pennies, and halfpennies. It was ordered that these coins should be stamped with the Prince of Wales's plume of feathers on both sides to which was also added an 'open book' which was Bushell's private mark. Coins were minted from from 1638 till 1642 when, in September, the mint was moved to Shrewsbury. It only lasted for about 3 months in Shrewsbury before it was moved to Oxford. The 'plume' and 'open-book' marks can be found on coins dated 1643 and 1644 indicating that these marks were used for several years after the mint left Aberystwyth. These marks can also be found on coins that have the 'ox' mark of the oxford mint.
