1941 F Germany 5 Reichspfennig Zinc  - WWII 

The zinc 5 Reichspfennig coin was minted by Nazi Germany between 1940 and 1944 during World War II, replacing the bronze-aluminium version, which had a distinct golden color. It was worth 1⁄20 or .05 of a Reichsmark. Made entirely of zinc, the 5 Reichspfennig is an emergency issue type, similar to the zinc 1 and 10 Reichspfennig, and the aluminium 50 Reichspfennig coins from the same period.
