...Did I mention its a gold coin? My first. Figures, I cant identify it. Maybe someone out the can I.d. it? Appears to be of arabic design. Thin with milling. Will send better photo of the coin.
After researching it, it appears to be an ottorman turkish coin. The examples I saw was made with 22k gold. You may be right about a piece of jewelry because I couldnt explain why it was found in a farm field here in NH.
