The halfpenny stamp was introduced following a reduction in the postal rate for newspapers and postcards. It was designed to be approximately half the size of the corresponding one penny stamp and is notable for being the smallest UK postage stamp ever issued at 17.5mm ×14mm (0.69in ×0.55in).[1]
The stamps (nicknamed "Bantams" due to their small size) were printed in sheets of 480 (20 horizontal rows of 24 stamps). They were line engraved and featured a bust of
Queen Victoria in profile with "½d" on either side.
A plate number was engraved in the design, in the left and right side lace work. The plates were numbered from 1 to 20, but plates 2, 7, 16, 17, and 18 were not completed, plates 21 and 22 were not used and plate 9 is now scarce because it was a rarely used reserve plate. The stamps were watermarked with the word "halfpenny" that extended across three stamps.[2][3]
