Hope it's OK to re-post this here (I originally posted it in the general ID
forum; nobody there could
help, maybe posted in the right
forum and with a clearer photo I'll have more luck)
This is an approx.12-14mm
cast bronze coin, thin and irregular in shape with a glossy black
patina. I'm fairly certain it's Middle Eastern and probably
Islamic, though beyond that I don't have a clue! One
side of the coin has a pattern of lines which resemble an M or an E, or possibly a trident, depending on the angle. The other
side has a similar (identical)? but fainter pattern.
