The Executive Board of the Riksbank decided in June 2004 that a special banknote would be issued to commemorate the 250th anniversary of the founding of Tumba Bruk banknote paper mill. The issuance date for the banknote is 26 May 2005. The banknote is legal tender.
2. Mother Sweden in intaglio print. The same design as executed by Julius Kronberg for the 1890 banknote series.
3. A watermark depicting the Swedish lion from 1835-1858 and a royal crown.
4. A holographic window thread that when held up to the light shows the “three crowns”, which changes to the denomination "100" when the note is held at an angle. When light is shone through it, the thread reads as a black line with a negative text of "100".
5. An intaglio print minitext "Kongl. Maj:ts Nådiga Kungörelse af then 20 Decembris 1754" (His Royal Majesty’s gracious notice of the 20th December 1754).
6. A blueprint of Tumba Bruk mill from 1804.
7. A minitext based on a decision by the Riksbank council in 1755, announcing that the bank intends to found a paper mill in Tumba.
8. A picture of paper manufacturing from Denis Diderot’s French encyclopaedia from 1751-1780.
Size: 92 x 170 millimetres
The main motif of the banknote is Mother Sweden. The text 2005 TUMBA BRUK 250 ÅR (2005 TUMBA BRUK 250 YEARS) can be found below the vignette. At the bottom of the banknote is a horizontal minitext with a Swedish text: "Then som thenne Sedel efterapar skal warda hängd; Men then, som bewisligen uptäcker efteraparen, skal undfå Fyratio Tusende Daler kopparmynt Præmium, enligit Kongl. Maj:ts Nådige Kungörelse af then 20 Decembris 1754." (rough translation: Anyone who counterfeits this note shall be hanged; but anyone who demonstrably discovers a counterfeiter shall receive forty thousand dalers in premium copper coins, according to proclamation by His Royal Majesty on the 20th of December 1754.)
The main motif on the reverse of the banknote is a blueprint of Tumba paper mill from 1804 and a picture from the Diderot Encyclopaedia 1751-1780, showing paper manufacture.
Along the length of the banknote, midway between the two main motifs are two lines of minitext with a Swedish text: "Den 14 juni 1755 beslutade fullmäktige att hos Kungl. Maj:t söka tillstånd att vid Tumba anlägga ett pappersbruk för bankens räkning, där till erhållande af nya och till efterapande svårare formulärer för de nu brukliga bankotransportsedlarna skulle tillverkas ett eget, med vissa ifrån allt annat papper särskilde, och till kompositionen ej lätteligen utrönta kännetecken utmärkt papper, med vilkets förfärdigande skall fordras en noga förvarad hemlighet" (rough translation: On the 14th June 1755 the Riksbank Council decided to apply for permission from His Royal Majesty for the Riksbank to found a paper mill at Tumba where the manufacture of new and more difficult to counterfeit forms for the now common bank transport bills would be carried out on the bank’s own, special paper with a composition that could not easily be copied and would remain a closely guarded secret.)
The colour of the paper is ivory. The left-hand side of the banknote carries a watermark that can be seen when the note is held up to the light. This depicts the Swedish lion, which was the main motif of the 10-riksdaler Banco note in 1850. The water mark also contains a picture of a royal crown.
The paper contains a broad window thread running through in a vertical line and showing either the denomination 100 or the lesser national coat of arms without escutcheon, depending on the angle in which light is reflected. This can also be seen as a dark line with the text 100 KRONOR when light is shone onto it.
