It looks to be a 1 Reichspfennig minted in Stuttgart (F on the reverse).
As I say, worth displaying along with badges etc as are things like bus tickets and such to add some context or background to your display.
Ps These are mint indicators I have come accross before but not being a coin buff I can't say if there should be 'H' marks;
A = Berlin.
B = Vienna. Also known as Wien.
D = Munich.
E = Muldenhutten.
F = Stuttgart.
G = Karlsruhe.
J = Hamburg

"War is an ugly thing, but not the ugliest of things. A man who has nothing for which he is willing to fight, nothing he cares more about than his own personal safety, is a miserable creature with no chance of being free unless made and kept so by the exertions of better men than himself."
It's nothing special and not even from the wartime, look at the year it is dated. In war they were made out of zinc, this earlier pieces are out of copper if I remember correctly.
Thanks so much guys, cool to know it was before the war and went through the entire war
It's still a neat piece and it sounds as though the price was right.
A complete list of these marks can be found on this German language Wikipedia page:
A, D, F, G and J are still in use today and appear on German Euro coins.
