Halfpenny of Henry VI
This coin was found very recently by Oliver Jackson. I was asked to provide further details, including a valuation.
The coin is a halfpenny of Henry VI. In the legend on the obverse there is a rosette before REX. On the reverse the legend reads VIL LA CAL IS, with a mascle after LA and a rosette after IS. Therefore, this coin was struck at Calais during the rosette mascle coinage of Henry VI. In the Standard Catalogue it is listed as number 1871.
Valuation
This is a reasonably decent example of the reign, denomination, type and mint and to a collector it should be worth £40 – £50.
