Not an expert on these coins but the one on the right reads: "ALFONSVS REX CASTELLE ET LEGIONIS" (Alphonse king of Castille and Leon) similar to
this coin,
this one, and others. You can clearly see the castles and lions on the reverse.
The one on the left is also from Castille and Leon, but from one of the Henry's ("ENRICVS REX CAST / ENRICVS REX LEGA") with castle on one side and lion on the other.
Both look way too nice to be original coins from the 13th/14th century, IMHO
