Watch List notes:

British Coins and Medals, Benedetto Pistrucci (1783-1855), an original white wax portrait design, seemingly for the farthing of the first issue copper coinage of George IV, c.1821, the left-facing draped bust, laureate with 13 leaves in wreath, tied behind the head with ribband, set onto a thin circle of slate, squared for scale, 103mm. (cf. Stefanelli, vol I, pl. 23; vol II, 42-51; cf. Peck pp.392-393, 1407-1416; cf. BDM IV, p. 617, somewhat similar piece illustrated; cf. Pyke, pp.108-111), expected surface hairlines, bruising and scuffs to wax, but a highly important discovery and an exceedingly rare survivor
The portrait is also very close to that chosen for the coinage, but the neck is not truncated, rather it descends into a mantle or gown. Other waxes by Benetto Pistrucci exist though most are now in Museum collections (see Stefanelli [Pirzio Biroli Stefanelli, Lucia, Roma, Museo della Zecca. Modelli in cera di Benedetto Pistrucci, Rome, 1989). (2000-3000 GBP)
