Roger Paul knew this coin was a penny of Edward III but he asked if I could give him some idea of its value.
On the obverse the legend reads EDWARDVS REX ANGLI and the letter R appears to have a wedge-shaped tail. On the reverse the legend reads CIVI TAS LON DON. The group of three pellets in each quarter has an annulet in the centre. Therefore, this penny was struck during the fourth coinage, pre-treaty period, series C.
The coin would grade nearly Fine but the reverse has been struck off centre. It’s not scarce so my price estimate in its present condition would be no more than £15.
