Especially with the Dutch around and their insistence on 25 cents and 2 1/2 Gulden coins and 25 Gulden notes and argh. Schilling? 1:7 ratio to the Mark the maths was atrocious. Italy tended to be nice, more or less exactly 1:1000, though of course that was because I was lucky and they didn’t inflate the currency between my visits.
