Sorry, that coin is not really worth anything. Made in Stuttgart, BW (mintmark F) some time between 1950 and 1965; they used a frozen date first. Total mintage for those 1950F 1 Pfennig coins: about 900 million. For this worn piece you would get €0.01 here in Germany. Why so much? Because its actual value is 0.51 cent - and that would be rounded up ... Christian
