This is a WWI Notgeld coin token from Nurnberg (Nuremberg), Germany, a Nurnberg-Further Strassenbahn transit token, themed Burg.  It's 24102.6 in the Menzel catalog.  It's aluminum, 24 mm across.  Take a look at the scanned images.  This would be a great addition to any collection.

I combine shipping on multiple items, and ship worldwide.  Please take a look at my many other notgeld and token listings in my Store.
