The Lost ValueEindhoven, 2021
Its an atempt to leak in the money circulation system.
Cyanotype coated money goes through the Counterfeit Detector.
Each time the value of the money is checked, the banknote gets darker and darker finally it loses all the value.
Counterfeit detectors use UV light to reveal authentication marks on bills. Reversing the process allows counterfeiting to be detected.
