George III was crowned
Yes, George III was crowned before the Boston Massacre. He ascended to the throne on October 25, 1760, and was officially crowned on September 22, 1761. The Boston Massacre occurred later, on March 5, 1770. Thus, his coronation took place nearly a decade prior to this significant event in American history.
Please check your coin. Any coin dated 1820 would be George III or George IV. George II died in 1760, 1820 sterling silver coins bearing the legend "Honi Soit Qui Mal Y Pense" (Evil to him who evil thinks) could be - George III Crown - St George and the dragon on the reverse - 37.6mm in diameter. George III Halfcrown - Crowned shield in garter on the reverse - 32mm in diameter. George III Shilling - Crowned shield in garter on the reverse - 23.5mm in diameter. George III Sixpence - Crowned shield in garter on the reverse - 19mm in diameter. Any medal with that legend would need to be described more fully.

King Arthur was not crowned King George; rather, he is a legendary figure from medieval British folklore. The title "King George" refers to several monarchs of the House of Hanover who ruled Great Britain, most notably King George III, who was king during the American Revolution. The confusion may arise from adaptations of Arthurian legends or modern retellings that blend historical and fictional elements, but there is no historical basis for King Arthur being crowned as King George.
