This is a nice H.D.A.G. Faehrmarke transit token from Hamburg Germany, DE 390 GZ in the Atwood catalog.  It's 24mm on a side.  Please use the scanned images to make your grading decision.  This would be a fine addition to any collection.

I combine shipping on multiple items.  Please take a look at my many other transit token, world coins by the pound and world coin listings.
