Hogespoorbrug in Zwolle (Netherlands)

The government of the city of Zwolle was lack of money so was forced to sell the church bell to Kampen. They tried to get a rather high price. Kampen accepted the deal, with the condition that they would choose the mode of payment. Zwolle accepted and Kampen paid with copper coins of four duiten. Local authorities counted the money with his hands so their fingers became blue after rubbing such amount of copper. So the citiezens of Zwolle are known as Blauwvingers ( Blue Fingers)
