I recently found remnants of a burglary in a small lake. A.o. there were a couple of foreign coins. Based on the remnants (membership cards, etc) I could deduce that the stuff had been there for about 12 years.
One of the coins happened to be a German 5 Pfennig coin. Cleaning it, it revealed 1950 (5 years after WWII).
The weird part :icon10: was that the coin had been split: it consists of only two thin slabs, the head side and the tail side. The middle part seems to be vanished!
I've been told that after the war copper was scarce. Maybe the coins had some inferior :death2: middle layer (zinc? during the war there were pure zinc coins). The coin has been on a nickle(?) 50 F Belgium coin. Though the Belgium coin was dissolved partly, it was not in the place where the German coin touched it. The photo probably is more illustrative.
Does anybody know about German coins? Is this a redox reaction?
