Singapore's Golden Jubilee (SG50) celebrations. 20 million pieces were printed for the commemorative SG50 banknote, while 15 million pieces of each commemorative SG50 design banknote were printed. There was an oversupply of these SG50 banknotes; by February 2016 only about less than half of them were actually issued.
