Go to this page and scroll down almost halfway...you can see that a nice one sells for $2 The one you have is interesting because the Germans were running out of copper/brass to make pfennigs because of the war so yours is made from zinc,a much cheaper metal.A couple of years later,the U.S. did the same thing for one year. http://www.luckylukeonline.com/Minor.html
Mexican Paso with the swastika on it lol. Not worth anything to sell, but cool to own, especially a WWII era one like you have their....for interests sake.
