I have no clue how to identify this coin. It is from Spain is all I can tell you. Anyone able to help me out on this one ?
I think it's below: Alfonso XI, (1312 - 1350 A.D.) Spain, Leon Billon Cornado O: +ALFON S REX, crowned bust left R: CASTELE LEGION•, castle with three towers; ME 1182; Burgos 289.
I could've told you Spain, definitely, but that's as far as I'd have gotten, so it's good @Mat stepped in.
