Well, the general design of a facing portrait one side and long cross with three pellets on the other was common at the time - mostly copying the design of English hammered coins.
The city named on the reverse (the "cross side" seems to be MEL ?D IEN SIS, "Melnodiensis" or some variant. I'm having trouble getting a match... the closest I've found is "Meldensis" for Meaux, France, but I haven't a detailed reference to know if that was a mint-city at the time in question. But I'd say it's definitely not an English mint.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
