One of only 4 known in existence. Of the highest rarity and importance, a PLATINUM trial piece struck from the obverse die of an 1812 pattern Bank of England 9 Pence token and a contemporary Farthing reverse, thus displaying "Georgius III" on the obverse but actually struck during the reign of George IV. Peck notes that the hardness of platinum led to difficulty in its striking, and as such the one or two examples known both show weakness in the obverse legend. This piece boasts handsome argent-gray surfaces, its elite hue far distinguished from silver, very sharply struck considering the difficulties in production. One of the most enigmatic and rarely offered types in the British pattern/numismatic series, auction record shows just one other specimen coming to market in the last two decades...Exceedingly Rare.
