This designer is known primarily for his reverses, with the portrait of the 1823 Two Pounds being the only obverse he engraved, using as a basis a model by Sir Francis Chantrey. Apparently, Pistrucci was unwilling to work from the model of another artist. The quality of the strike was exceptional, producing what some consider to be the most beautiful two pound piece ever produced. The reverse of this coin by Pistrucci has been the basis for the design of this denomination right up to the present day (2009 being the most recent). The 1824-1826 proof coins feature a smaller head of the king, with the legend GEORGIUS IV DEI GRATIA and the date, while the reverse shows a crowned shield within a mantle cape with the legend BRITANNIARUM REX FID DEF. The 1826 coin has the edge inscription DECUS ET TUTAMEN ANNO REGNI SEPTIMO. In 1831 a proof coin of this denomination was produced for the start of the reign of king William IV. The obverse shows a right-facing head of the king with the legend GULIELMUS IIII D G BRITANNIAR REX F D, while the reverse shows a crowned shield with the legend ANNO 1831. There is no edge inscription. The next appearance of the denomination was not until the Golden Jubilee of Queen Victoria in 1887. The Jubilee head was used with the obverse inscription VICTORIA D G BRIT REG F D, while the reverse shows Pistrucci's design of St George slaying the dragon with the only legend being the date in the exergue. The edge of this coin is milled, and it weighs 16 grams. This coin was also (rarely) produced in the mint at Sydney, Australia, which is identified by the letter "S" above the centre of the date. The Pistrucci reverse was used again in 1893, when the obverse used the "Old Head" of the queen, with the legend VICTORIA DEI GRA BRITT REGINA FID DEF IND IMP, and the edge is again milled. In the reign of King Edward VII, £2 coins were issued in 1902 and did circulate. The 1902 Edward VII coin was also minted at Sydney, being identified by an "S" above the centre of the date. For George V and George VI, £2 coins were only issued in proof sets in the first year of each reign.
