Michael Poole said he found this coin during an outing organised by his detecting club. Some enthusiasts detect alone, others only with their club. I prefer the latter, for I think it’s really great to be out and about with a group of likeminded individuals.
Michael’s find is a groat of Henry VI. It has rosettes in the obverse legend and rosettes and mascles on the reverse. Therefore, it is a product of the rosette mascle coinage of Henry VI. The mint signature on the reverse (CALI SIE) points towards it being struck at Calais, which was under English control when the coin was struck.
It would grade good Fine but the surface on both sides is discoloured. In its ‘as found’ condition I would give it a price range of £80 – £90.
