Today's selection brings us to the Netherlands, the land of wooden shoes, tulips, and windmills. Displayed is the 1997 issue 10 Gulden with it bright colors and geometric shapes. An unusual property about this note is that it is made of polymer. Due to the amount of wear highly circulated noted get many countries are switching to plastic. Tests have shown the polymer notes to last 10 years in heavy circulation. To put that in perspective the US $1 is replaced on an average of every 18 MONTHS! The black shape in the lower right is actually CLEAR and you can see through it. That is a counterfeiting counter measure.
