I received this coin on a swap and now I need your help with the ID. My swap partner only said medieval Italy, he doesn't know more than this.

Thanks in advance.
Citação: "radrick007"I have had help here previously with a medieval Italy coin so I'm sure someone will be able to help. Are you able to provide better images (higher res, brighter, closer, etc.)?These are the photos I have, used my friend's camera that is better than mine.
