The first regular milled silver pennies appeared around 1664 or 1665 and are undated, weighing 0.5 grams and being 12 mm in diameter. They show the king facing left, with I behind the head, inscribed CAROLVS II D G M B F & H REX, and the reverse shows a shield enclosing the Arms of England, Scotland, Ireland and France, inscribed CHRISTO AUSPICE REGNO. From 1670 to 1684 dated pennies were produced each year, showing the king facing right with the inscription CAROLVS II DEI GRATIA, while the reverse shows a crowned "C" with the inscription MAG BR FRA ET HIB REX date.
