Thanks, klaupo. I too think it's of that "political comment" genre, just like the Napoleon III piece you posted.
Others I can think of include the Kaiser and his hat on the post-WWI alterations of Prussian state coinage, the counter-marking of the Irish coins during the c.'1970s version of "the troubles," the communist/social counter-marking of the Italian 2-lire coins of the 1920s (expensive to own now!), and then there are the "Hobo" nickels from the U.S. which can perhaps be seen as political comment on the poverty of the 1930s--and then also the (sometimes amazingly intricate) Italian coppers of the 1860s recut to show VEII cncased in Papal headgear.
What I was wondering was whether the push-pull of Austrian politics of the 1930s left behind any well-recognized group of coins counter-marked like this 1930 1-groschen, or indeed some of the graffiti-inscribed German coinage of the '30s (which I have read about and heard mentioned in a contemporary movie, but have never encountered myself).
I know there probably isn't much widespread interest in all this, but it seems like a worthwhile subject for a small collection or maybe a short article.
Anyway, danke klaupo.
