Most probably this is not a coin but a one-sided token - poorly preserved. I found it in a world-coin-lot and I have no idea about its origin.
Weight: 5.52g
Diameter: 23mm
Material: brass (by view)

One side shows a head facing left with a short inscription above. It looks like "E CIMH" followed by an unrecogniseable sign. The other side seems to be plain.
Maybe someone knows a bit more about this type?
