Green spot by nose, toned good very fine and a little softly struck, extremely rare with the plain edge.
The Eimer reference is ”The Pingo Family & Medal Making in 18th Century Britain” where this coin is recorded as a pattern for a gold coinage and with either grained or lettered edge. This is very similar in design to the fourth bust type George III gold coins of 1774-86.
