Id'ing Medieval English Hammered Coin

Thanks Medieval. I'll post some clearer photos and the size when I receive the coin.

A mediaeval English hammered silver penny, is what it is. This basic design was issued after 1279, but unfortunately, I can't see if enough detail has survived on the obverse to be able to identify the king.

On the plus side, the mint-city named on the other side should be readable, which may also narrow down a date. The formula is CIVI | TAS | (first syllable of Latin city-name) | (second sylllable). I can clearly see the "CIVI" on the right side; the syllable in the top quadrant should therefore be the second syllable in the city name and appears to be "EME". I think the city of Durham (DVR | EME) is the best match. The Durham mint was under the control of the Bishop of Durham and the coins from there often feature unusual mintmarks or privy marks to denote their episcopal origin.

Thanks again all. The person who identified the coin for me said it was an Edward III penny minted in Durham by the bishop, a late pre-treaty (series G) or treaty period coin, thus from 1356-1369. They said the obverse letters would be EDWARDVS REX ANGLIE and the reverse CIVITAS DVREME (as Sapp said).
