Could this be a copper maravedi?

[ROBOTCOP13]

Found on the Treasure coast with the little bit of erosion we've been getting. I found it with my white's TDI when I got home and put it under my MX5 it id'ed at a 55 which is about a low range for copper. It's not attracted to a magnet like a lot of the similar looking iron flake that we get here. The green patina made me curious. Looks like a cross on one side. Trez you there, it was near your spot.

Commercial, yes looks like a 1/2 or a worn out 1 reales.The green is patina from the copper mixed in the silver.
Way to go.
