Help for identification - English coin [решено]

I need help to identify this coin. I suggest it is a penny, but period and type is unknown for me. Max diameter is 18,6 mm, weight is 1,16 gram, thickness is 0,6 mm. Composition is silver. I have also problem with grading of such old coins - what is reasonable?

Thank you in advance

The obverse legend appears to be ✠ EDWA R ANGL DNS HYB with no punctuation.

Reverse is CIVITAS LONDON.

With this, I think you can search through the pennies in England, and narrow it down.  (This might be close N#324328, but I think a UK exert can get an exact answer ).

Hello.

I think your 1p is an Edward II 1307 to 1327 and is Type 11 Group 11c  Sp# 1457 1310/1314.

Ian.

Thank you all. I was really confused even with Spink - COINS OF ENGLAND and Spink ENGLISH COINS 1180-1551 besides me. Do you have an idea of grading?
