It’s a quote from a poem by Goethe (https://gutenberg.spiegel.de/buch/gedichte-9503/52)
“Trutz” means “defiance”; Google Translate makes hash out of the phrase, but I think it means “All powers lend themselves to defiance” or something along those lines. In the context of an austerity coin issued by the Weimar republic, I don’t really know how to interpret it. (That is, I can think of several opposing but equally believable interpretations, depending on which political faction was in charge of issuing the notgeld.)
