Here we have a voided long cross penny of Henry III. The finder, George Bates, asked if I could provide him with the class, mint and moneyer.
On the reverse the legend reads RIC ARD ONL VND, so the moneyer is Ricard and the mint London. Various characteristics mark out the coin out as being an example of long cross class Va2.
The obverse has been struck off centre and so has the reverse, though not as far off as the obverse. It’s a peculiar colour, which might be due to the ground conditions that it has been in for several hundred years. It would grade Fine but with the offset strike and the slightly off-putting colour my best price estimate would be £18 – £20.
