The finder of this hammered silver coin, Glyn Peak, asked if I could let him have a valuation on it. It’s a penny of Edward I, which is fairly common but its state of preservation is better than most examples I see as detecting finds.
The obverse has characteristics that point towards the coin being an example of class 10c-f. Several sub-classes are on record, mostly relating to differences in the crown worn by the king. However, in my opinion the differences are minor and uninteresting so I group them all together as 10c-f. The legend on the reverse, CIVI TAS LON DON, tells us that this penny was struck at London.
The reverse has been struck off centre but Glyn’s find is otherwise in about VF condition, so to a collector it should be worth around £35.
