Head Coin.jpg

trident1 coin1.jpgHi im really new to this site and collecting coins.I was hoping someone could help give me any info like city made when it was made and what the things on it are. Each picture is a different coin theyre one sided.

Can any one out there help me in identifying this coin. I was told it may pre date the Roman era and could be Greek. It is also tilted a little to the right when I scanned it.
