Yes that is one of the french coins i was refering too that are more often counterstamped than the english coinage. I am not sure if there was a law that stated the king (or queens) coin should not be defaced back them but I am sure this never applied to foreign coin (which would mostly circulate in london bristol or hull and liverpool) I would presume. I would also presume that the populace would also find english coins that are defaced , to say the least,objectionable and at the worst unacceptable
