1717 marks the year when the denomination of the “Guinea” was first named in official mint papers and proclamations. Sir Isaac Newton was responsible for calling it this in his official papers as Master of the Mint setting the value at 21 Shillings for a Guinea which now remained constant after many years of fluctuation. The coin was previously known as a Twenty Shilling piece in official papers but had colloquially been called a “Guinea” by the wider population since the time of Charles II on account of the fact the gold (with the elephant provenance mark) emanated from Guinea in Africa.
