Three halfpence (English coin)
The English three halfpence, a silver coin worth 1½d, was introduced in Elizabeth I of England's third and fourth coinages (1561-1582) as part of a plan to produce large quantities of coins of varying denominations and high metal content. The obverse shows a left-facing bust of the queen, with a rose behind her, with the legend E D G ROSA SINE SPINA -- Elizabeth by the grace of God a rose without a thorn -- while the reverse shows the royal arms with the date above the arms and a mintmark at the beginning of the legend CIVITAS LONDON -- City of London, the Tower Mint.
The three-halfpence coin closely resembles the English Three Farthing coin and the Threepence coin, which differed only in the diameter. This is 16 millimetres in an unclipped coin, compared to 14 mm for the three-farthings, and 19 mm for the three pence (except 1561, which was 21 mm).
