Charles's hammered pennies produced at the Tower originally had a design of a rose on both sides, with the inscription C D G ROSA SINE SPINA on the obverse and IUS THRONUM FIRMAT — "Justice strengthens the throne" — on the reverse. Later pennies bore a bust of the king facing left with a I behind the head to denote the denomination of one penny, with the inscription CAROLUS D G MA B F ET HI REX — "Charles by the grace of God King of Great Britain France and Ireland", while the reverse shows an oval shield and the IUSTITIA THRONUM FIRMAT inscription. Following the takeover of the Tower mint by the English Parliament in 1642, the same coin designs were produced until 1648 though with an older-looking bust of the king; this was to emphasise the fact that Parliaments' argument was not with the king but with his "evil advisors".
