In 1874, notes were introduced by the [[Sveriges Riksbank|Riksbank]] in denominations of 1 krona and 5, 10, 50, 100 and 1,000 kronor. The 1 krona was only initially issued for two years, although it reappeared between 1914 and 1920. In 1939 and 1958, 10,000-kronor notes were issued.

Production of the 5-kronor note ceased in 1981, although a coin had been issued since 1972. With the introduction of a 10-krona coin in 1991, production of 10-kronor notes ceased and a 20-kronor note was introduced.

All remaining one krona banknotes became invalid after 31 December 1987. All remaining five krona and ten krona banknotes became invalid after 31 December 1998.<ref>{{cite web |url=https://www.riksbank.se/en-gb/payments--cash/notes--coins/notes/invalid-banknotes/banknotes-that-became-invalid-prior-to-2016/10-000-krona-banknotes/ |publisher=[[Sveriges Riksbank]] |title=10,000-kronor banknotes |date=4 May 2018 |access-date=21 July 2019}}</ref>

An exhaustive list of every banknote design since 1874 is not included, but the following five designs were or will be retired in 2016–2017. The oldest design began to be printed in 1985.

A 20-kronor banknote (a new denomination) was printed 1991–1995 with a portrait of the writer [[Selma Lagerlöf]] and on the reverse was an engraved interpretation of a passage from the book ''[[The Wonderful Adventures of Nils]]''. The banknote became invalid after 31 December 2005. A more secure version with the same portrait was printed from 1997 to 2008 and became invalid after 30 June 2016.

A 50-kronor banknote (3rd design since 1896) was printed 1996–2003 with a portrait of the singer [[Jenny Lind]] and on the reverse was a picture of a [[Nyckelharpa|silver harp]] and its tonal range. The banknote became invalid after 31 December 2013. A more secure version with the same portrait was printed from 2006 to 2011 and became invalid after 30 June 2016.

A 100-kronor banknote (3rd design since 1898) was printed 1986–2000 with a portrait of the botanist [[Carl Linnaeus]] and on the reverse was a drawing of a bee pollinating a flower. The banknote became invalid after 31 December 2005. A more secure version with the same portrait was introduced in 2001 and became invalid after 30 June 2017.

A 500-kronor banknote (a new denomination) in a blue shade was introduced in 1985 with a portrait of [[Charles XI of Sweden|King Charles XI]] and on the reverse an engraving depicts [[Christopher Polhem]], the "father of Swedish engineering". These banknotes became invalid on 31 December 1998. A 500-kronor banknote (red, but without foil strips) with the same portrait was printed 1989–2000. This banknote became invalid after 31 December 2005. A more secure version with the same portrait was introduced in 2001 and became invalid after 30 June 2017. The banknote had some controversy in 1985 because of the executions of "[[Snapphane]]" guerrilla warriors that King Charles XI ordered.<ref>{{cite web|url=https://www.expressen.se/kvp/kronikorer/erik-direkt/erik-direkt-karl-xi-hade-behovt-baten/|title=Karl XI hade behövt båten|language=sv|date=10 July 2010|work=[[Expressen]]|access-date=21 July 2019|archive-date=30 June 2018|archive-url=https://web.archive.org/web/20180630062908/https://www.expressen.se/kvp/kronikorer/erik-direkt/erik-direkt-karl-xi-hade-behovt-baten/|url-status=live}}</ref>

The first two designs of 1,000-kronor banknotes (printed from 1894 to 1950 and 1952–1973) became invalid on 31 December 1987. The third design with portrait of [[Charles XIV John|King Charles XIV John]] and [[Jöns Jacob Berzelius]] (printed 1976–1988) and declared invalid on 31 December 1998. In preparation for retirement of the 10,000-kronor banknotes a new 1,000-kronor banknotes (of the 4th design / without foil strips) was printed from 1989 to 1991 with a portrait of [[Gustav I of Sweden|Gustav Vasa]] and on the reverse a harvest picture from [[Olaus Magnus]]'s [[A Description of the Northern Peoples|Description of the Northern Peoples]] from 1555. Circulation peaked at over 48 million in 2001.

On 15 March 2006, the Riksbank introduced a new, more secure 1,000-kronor banknote with the same portrait and the Riksbank became the first central bank in the world to use the security feature of MOTION (a moving image in the striped band) on the new 1,000-kronor banknote. When the banknote is tilted, the picture in the striped band appears to move.<ref>{{cite web |url=http://archive.riksbank.se/en/Web-archive/Published/Press-Releases/2006/Riksbank-to-introduce-new-more-secure-50-and-1000-krona-banknotes/ |publisher=[[Sveriges Riksbank]] |title=Riksbank to introduce new, more secure 50 and 1000-kronor banknotes |date=6 March 2006 |access-date=21 July 2019}}</ref> The Vasa banknote without security thread became invalid after 31 December 2013 at which time there was only 10 million in circulation. The Vasa banknotes with the security thread became invalid after 30 June 2016 at which time there was under 4&nbsp;million in circulation. Replacement banknotes featuring [[Dag Hammarskjöld]] became valid on 1 October 2015, but were circulated in considerably fewer quantities (less than 3.5&nbsp;million), thus reducing the supply of cash in Sweden.

The 10,000 krona banknote was always printed in small quantities as it was one of the most valuable banknotes in the world. The first design featuring the Head of [[Mercury (mythology)|Mercury]] was printed in 1939 and became invalid after 31 December 1987. The second design was printed 1958 and featured a portrait of [[Gustaf VI Adolf of Sweden|Gustav VI Adolf]], and became invalid after 31 December 1991.

Invalid banknotes can be redeemed via the Riksbank, with an administration fee of 200 kronor.
