William Chaloner
William Chaloner (c. 1650 – 16 March 1699) was an English counterfeiter and confidence trickster whose operations targeted the coinage and early paper currency of late seventeenth-century Britain amid the economic disruptions of the Great Recoinage of 1696.[1]Born in Warwickshire to a weaver's family, Chaloner apprenticed briefly before fleeing to London, where he progressed from hawking wares and pickpocketing to mastering sophisticated forgery techniques, including the gilding of base metals to mimic gold coins like guineas and the milling of edges to replicate official minting.[1] His ventures extended to falsifying seals, Malt Lottery tickets, and Bank of England notes, yielding an estimated £30,000 in illicit gains over seven to eight years and funding a lavish existence with a Knightsbridge residence and carriage.[2][1]
Chaloner supplemented coining with scams such as fabricated Jacobite plots, posing as an informer to extract bribes from authorities, and survived multiple Newgate imprisonments and trials through witness intimidation or evidentiary gaps.[2] His downfall came via Isaac Newton, Warden of the Royal Mint from 1696, who deployed agents, conducted over 100 interrogations in disguise, and secured testimony from eight accomplices, leading to Chaloner's conviction for high treason on 3 March 1699 and public hanging at Tyburn.[1][2] Newton's pursuit exemplified rigorous enforcement against a forgery epidemic that threatened national finances, prosecuting 28 criminals in total during his tenure.[1]
