The original reverse of the bronze version of the coin, designed by Leonard Charles Wyon, is a seated Britannia, holding a trident, with the words HALF PENNY to either side.
Issues before 1895 also feature a lighthouse to Britannia's left and a ship to her right.
Various minor adjustments to the level of the sea depicted around Britannia, and the angle of her trident were also made over the years.
Some issues feature toothed edges, while others feature beading.

Over the years, various different obverses were used.
Edward VII, George V, George VI and Elizabeth II each had a single obverse for halfpennies produced during their respective reigns.
Over the long reign of Queen Victoria two different obverses were used, but the short reign of Edward VIII meant no halfpennies bearing his likeness were ever issued.

During Victoria’s reign, the halfpenny was first issued with the so-called ‘bun head’, or ‘draped bust’ of Queen Victoria on the obverse.
The inscription around the bust read VICTORIA D G BRITT REG F D. This was replaced in 1895 by the ‘old head’, or ‘veiled bust’.
The inscription on these coins read VICTORIA DEI GRA BRITT REGINA FID DEF IND IMP.

Coins issued during the reign of Edward VII feature his likeness and bear the inscription EDWARDVS VII DEI GRA BRITT OMN REX FID DEF IND IMP.
Similarly, those issued during the reign of George V feature his likeness and bear the inscription GEORGIVS V DEI GRA BRITT OMN REX FID DEF IND IMP.

A halfpenny of King Edward VIII (1936) does exist, dated 1937, but technically it is a pattern coin i.e. one produced for official approval; it would probably have been due to receive this approval at about the time that the King abdicated.
The obverse shows a left-facing portrait of the king (who considered this to be his best side, and consequently broke the tradition of alternating the direction in which the monarch faces on coins — some viewed this as indicating bad luck for the reign); the inscription on the obverse is EDWARDVS VIII D G BR OMN REX F D IND IMP.

The pattern coin of Edward VIII and regular issue halfpennies of George VI and Elizabeth II feature a redesigned reverse displaying Sir Francis Drake's ship the Golden Hind.

George VI issue coins feature the inscription GEORGIVS VI D G BR OMN REX F D IND IMP before 1949, and GEORGIVS VI D G BR OMN REX FIDEI DEF thereafter.
Unlike the penny, halfpennies were minted throughout the early reign of Elizabeth II, bearing the inscription ELIZABETH II DEI GRA BRITT OMN REGINA F D in 1953, and ELIZABETH II DEI GRATIA REGINA F D thereafter.
