As well as a whole penny of Henry III this week, we have a voided long cross cut halfpenny, which was found by Paul Marland.
The coin will belong to class 3 but I can’t see enough of the obverse to be able to pin it down to a sub-class. What remains of the reverse legend reads NIC OLE, which is the name of the moneyer. The mint is uncertain as an official named Nicole was employed at three different mints.
This cut halfpenny would grade VF but it has a crack on the centre line. It would be worth no more than £2, purely because detectorists have dug up tens of thousands of similar coins.
