The 2009 series of Danish Banknotes commenced in August 2009 and replaced the 1997 series. The theme of the notes is bridges of Denmark and ancient Danish artifacts found in the vicinity of the bridges. Danish artist Karin Birgitte Lund was selected to design the 2009 series after a competition.[1] The competition specified the bridges theme as mandatory, and it was her idea to include the artifacts on the reverse side.
The sizes of the 2009 bank notes are identical to the 1997 bank notes, in order to avoid alterations to automated teller machines. The height is 72 millimetres and the lengths are from 125 mm to 165 mm, increasing by 10 mm for each new value.
The Danish central bank has, as of 2020, been upgrading the 2009 series to make it more secure against counterfeiting.[2] The upgraded banknotes constitute the 2009A series. The 1000-krone banknote will not be upgraded, as it is due to be phased out along with all banknotes made before the 2009 series on 31 May 2025.[3][4]
