He didn't and it's not.

Took a chance and found it listed in Cobwright as G.0504B0418 It is an evasion piece These were contemporary counterfeits with either deliberate misspellings in the legend, completely different legends, or "impossible" coins. This is a combination of a mispelled legend GEORGIUS instead of GEORGIVS, and a coin of George II dated eleven years after he died.

The British government did not issue much in the way of coinage during the last third of the 18th century, and most of what they issued was gold and silver. Except for a moderate issue of farthings and half pence from, 1771 to 1775 no copper, the coins of the average man, was issued between 1740 and 1797. By the 1780s, 90% of all the coins in circulation were evasions or outright counterfeits. That was why the Conder tokens came into existance. Tokens of good copper, of full legal weight or better, and redeemable by large businesses and local merchants that the people knew and saw every day. The people had such faith in the Conder tokens that they actually forced the good legal tender out of circulation. Prices were higher if purchased with Government coinage than with local tokens.
