Uniface Trial Reverse for a Sovereign of 1824 struck in Lead
George IV, Uniface Base Metal Trial Reverse for a Sovereign, 1824, struck in lead on a very thick flan, by Benedetto Pistrucci, St George, helmeted with streamer and cloak, slaying dragon right with sword, broken lance on ground, initials WWP on ground-line, date in exergue, no upper serif on the 1, BP without stops in exergue, all within a linear raised circle, 10.43g, 21.8mm to 22mm, thickness 2.5mm (WR -; Douglas-Morris -; cf S 3800). Scratched and striated on plain side, "squeezed" in lead from the die and of ovoid form, rim bruise with a number of tiny digs and a patina of light oxidation, otherwise extremely fine, perhaps unique.
bought A H Baldwin & Sons Ltd, March 2006
Trials of this nature are usually only ever "squeezed" from a working die in uniface format in base metal because impressions can be taken from an unhardened die. Silver and gold require a hardened die, after which further work on the die is not possible.
Estimate: £800-1000
