In the short reign (1547–1553) of King Edward VI there were several issues of halfpennies. The first issue was produced between April 1547 and January 1549 at the Tower and Bristol mints; both mints' products are extremely rare and have the crowned bust of the king on the obverse, with the inscription EDG ROSA SIN SPIN (or EDG DG ROSA SIN SPIN on some Bristol coins) and a cross with CIVITAS LONDON or CIVITAS BRISTOLI on the reverse. The final issue of halfpennies was produced at the Tower mint between 1550 and 1553 with the obverse legend being EDG ROSA SINE SPINA surrounding a rose in the centre of the coin, and the reverse showing CIVITAS LONDON around the royal shield over a cross. The quality of silver in this final issue of halfpennies was so poor that the coin was often used as a farthing.
