This one is about the diameter of a US nickel. On one side, a griffin in a circle, with a crown on top of the circle. On the left side "HESSEN" on the right side "DARM"
On the other side, "*I*" below that "Pfennig" at the bottom edge
"R-F"
This coin has hole drilled through it, about 1 mm in diameter, it looks like it was punched through with something.
ANy ID help appreciated. Oh yeah, there's no date on this one.
