I make the date as 1223/30, which seems to equate to 1836. I think the denomination is 5, but I'm less certain. It looks copper but could be billon. It's about the size of a nickel. With this info you'd think I could ID it but I can't find a match. It has to either be from Turkey or Egypt. Help?
My first impression is a 5 Kuruş of the Ottoman Empire, but the diameter would be 39mm, compared to a U.S. nickel (21.21mm). Here is the Numista link. I believe you are correct in assuming billon.
