Charles Clarke (20 February 1719 – 16 November 1780) was an English numismatist and antiquarian. He served as vicar of Elm from November 1762.
Clarke was born in Kensington, into the supposedly ancient Clarke family. He attended Oxford from 1736, where he failed to graduate, going on to take holy orders. Clark's first and only numismatic work Some conjectures relative to a very antient piece of money (1751), which incorrectly identified a recently discovered coin, proved to be an utter failure. It was refuted swiftly and unsympathetically by numismatist George North, who correctly identified the coin as a common Peny-yard pence.
Even if some unassociated conclusions were true, Clarke was humiliated, feeling his "reputation and character" damaged by North's response. Clarke attempted some later publications, including a bitter refutation of one of North's works, but none ever came to fruition. Other than his Conjectures and a poorly regarded genealogy (published posthumously), none of Clarke's antiquarian work survives. Feeling a conspiracy against him, Clarke stopped paying his dues to the Society of Antiquaries, and was finally kicked out in 1765. In 1762, he retired to Elm, serving as a vicar, where he remained for the rest of his life.
