I'm not sure that I understand your question. I'll try to describe the political and monetary situation in that region.
WW1 ended in December 1918, and one of results was the crash of the Austro-Hungarian empire and the creation of several new countries: Czech republic, Hungaria, Kingdom of Yugoslavia, (maybe, I'm not sure) Romania, Fiume (as a free city)... Austro-Hungarian money soon started to loose it's value, and those new countries decided to "mark" or "validate" A-U kroner found on their territories, to prevent circulation of fresh printed (and worthless) A-U kroner.
You can try to put this document into Google translate (Croatian->English), the result is actually quite good (one thing: Rijeka means river, but I don't think that there's any river in the city of Rijeka )
best regards
