Henry VI Half Groat

It’s a Henry VI halfgroat, which was struck at Calais during the annulet coinage. The photographs were enlargements of the coin, which can sometimes be confusing if the same design and legends were used on groats. However, on groats the inner legend on the reverse reads VIIL LA CALI SIE but on halfgroats the mint signature is CAL IS’. The coin would grade VF in terms of wear but there are faint scratches on the obverse, which is also double struck and this will reduce its possible commercial value.
