The trouble with the florins of Deventer was that no one took them seriously. This Dutch mint was starved for work as the federal government tried to close the small mints with medieval minting rights granted by the German emperor. It must have been a tortuous-thinking lawyer who came up with the solution: if we can't strike Dutch coins, let's strike German coins.
They called it a florin and said it was worth 28 stuiver, but it was lightweight both in the Holy Roman Empire and in the Republic. What saved the issue was a "silver hunger" in Germany, that made any coin, especially large silver coins, aceptable in trade. It took a war in 1672 to close the legal loophole. Curiously, the English long thought that florin was another word for gulden. An indication of which ignorant foreigners the lightweight coins were unloaded on?
In their fear that the coin would not be accepted, the good people of Deventer imitated two German designs, both of which carried the value 28 (stuivers). On one side it is in the orb, on the other in a cartouche below the shield.
