Hi it is impossible to tell without a picture but the figure may be a walking or rampant lion the reverse is the symbol of Castille and the obverse Lion ( Catilla y Leon ) and probably the denominatio is a maravedis

here a 2 maravedis
that is a 4 but your may be a smaller denomination and probably dark copper.
