This one seems pretty rare, but who knows. It was the same price as the Camac Kyan one. Its in pretty nice condition.
Its rated Common. This is mule 3, leaving 4 mules left with the Wilkinson reverse (5 if you include multiply dated mules).


Im guessing that the die sinkers in question sank the dies for Wilkinson and struck this as an advertisement peice.
Onto pastures new - next up is the RULE BRITANNIA mule which I believe has a double mule - a 3rd tokens edge lettering, but it is yet to be known.
