Watch List notes:

The Pavilion Collection, Commemorative Medals, George IV, Royal Society of London, Royal [or King's] Medal, specimen striking in copper, 1826, by William Wyon, bare head l., after Chantrey, GEORGIVS IIII REX SOC REG LOND PATRONVS, rev. standing figure of Newton, from Roubiliac's statue in Trinity College, Cambridge, holding scroll, with drawings of his theories either side, REGIS MVNIFICENTIA ARBITRIO SOCIETATIS, 72.5mm. (BHM.1271,R4; Eimer 1186; Carlisle pp.182-188), a little scuffed and bruised, very fine and exceedingly rare
The Royal Collection has specimens of the Society's Royal Medals for all other monarchs to the present Queen, but lacks a medal of George IV. On the medal's reverse the drawing to the left displays the solar system whilst that on the right, the sixty-sixth proposition of his (Newton's?) 'Principia'. Today's medals carry the same reverse design, though the medals themselves are now gilt-silver. The first recipients in 1826 were John Dalton, 'For his development of the Atomic Theory...' and James Ivory, 'For his Paper on Astronomical Refractions...' However, the ten recipients of the medals awarded between 1826 and 1830 had to wait till the reign of William IV before they received them.
