Vintage Sterling Marcasite Our Lady of Guadalupe Small Pendant Charm Sized

Good condition vintage Our Lady of Guadalupe pendant or religious medal- there are no missing marcasites. The medal is marked sterling (but it is partially obscured or rubbed off) and also has another makers mark- that I can't make out (either the maker or possibly indicating that the insert with Our Lady is gold). The medal measures approximately 11/16ths inches tall without the bail. This is a lovely vintage medal that would be suitable to wear on a chain or on a charm bracelet. Please note the pendant is in tarnished, uncleaned condition.
