10 euro note

The changeover period during which the former currencies' notes and coins were exchanged for those of the euro lasted about two months, going from 1 January 2002 until 28 February 2002. The official date on which the national currencies ceased to be legal tender varied from member state to member state.[4] The earliest date was in Germany, where the mark officially ceased to be legal tender on 31 December 2001, though the exchange period lasted for two months more. Even after the old currencies ceased to be legal tender, they continued to be accepted by national central banks for periods ranging from ten years to forever.[4][17]

Design for the first series of ten euro notes

Obverse

Reverse

Notes printed before November 2003 bear the signature of the first president of the European Central Bank, Wim Duisenberg, who was replaced on 1 November 2003 by Jean-Claude Trichet, whose signature appears on issues from November 2003. Notes issued after March 2012 bear the signature of the third president of the European Central Bank, incumbent Mario Draghi.[5]

A new series, similar to the current one, was released on 23 September 2014.[18] The European Central Bank will, in due time, announce when banknotes from the first series lose legal tender status.[18]

The first series issues do not reflect the expansion of the European Union: Cyprus is not depicted on those notes as the map does not extend far enough east; Malta is also missing as it does not meet the first series' minimum size for depiction.[19]

Since the European Central Bank plans to redesign the notes every seven or eight years after each issue, a second series (Europa series) of banknotes was already in preparation in 2012. New production and anti-counterfeiting techniques are employed on the new notes, but the design is of the same theme and similar colours of the current series; bridges and arches. However, they are recognisable as a new series.[20]

As a lower value note, the security features of the ten euro note are not as high as the other denominations, however, it is protected by:

• A hologram,[2] tilt the note and one should see the hologram image change between the value and a window or doorway, but in the background, one should see rainbow-coloured concentric circles of micro-letters moving from the centre to the edges of the patch.[23]
• A EURion constellation,[2]
• Special printing processes give the euro notes their unique feel.
• A glossy stripe,[2] tilt the note and a glossy stripe showing the value numeral and the euro symbol will appear.
• Watermarks,[2] it appears when the banknote is against the light.
• Raised printing,[2] special methods of printing makes the ink feel raised or thicker in the main image, the lettering and the value numerals on the front of the banknotes. To feel the raised print, run your finger over it or scratch it gently with your fingernail.[24]
• Ultraviolet ink,[2] Under ultraviolet light, the paper itself should not glow, fibres embedded in the paper should appear, and should be coloured red, blue and green, the European Union flag looks green and has orange stars, the ECB President signature turns green, the large stars and small circles on the front glow and the European map, a bridge and the value numeral on the back appear in yellow.[25]
• Microprinting,[2] On numerous areas of the banknotes you can see microprinting, for example, inside the "ΕΥΡΩ" (EURO in Greek characters) on the front. You will need a magnifying glass to see it. The tiny text is sharp, and not blurred.[25]
• A security thread,[2] The security thread is embedded in the banknote paper. Hold the banknote against the light - the thread will appear as a dark stripe. The word "EURO" and the value can be seen in tiny letters on the stripe.[26]
• Perforations,[2] Hold the banknote against the light. You should see perforations in the hologram which will form the € symbol. You should also see small numbers showing the value.[26]
• A matted surface,[2] the note paper is made out of pure cotton, which feels crisp and firm, but not limp or waxy.[24]
• Barcodes,[2]
• A serial number.[2]

• Watermark: When the note is held under a normal light source, a portrait of Europa and an electrotype denomination appear on either side.
• Portrait Hologram: When the note is tilted, the silver-coloured holographic stripe reveals the portrait of Europa-the same one as in the watermark. The stripe also reveals a window and the value of the banknote.
• Emerald Number: When the note is tilted, the number on the note displays an effect of light that moves up and down. The number also changes colour from emerald green to deep blue.
• Raised Printing: On the front of the note, there is a series of short raised lines on the left and right edges. The main edge, the lettering and the large value numeral also feel thicker.
• Security Thread: When the note is held against the light, the security thread appears as a dark line. The Euro symbol (€) and the value of the banknote can be seen in tiny white lettering in the thread.
• Microprint: Tiny letters which can be read with a magnifying glass. The letters should be sharp, not blurred.
• Ultraviolet ink: Some parts of the banknote shine when under UV or UV-C light. These are the stars in the flag, the small circles, the large stars and several other areas on the front. On the back, a quarter of a circle in the centre as well as several other areas glow green. The horizontal serial number and a stripe appear in red.
• Infrared light: Under infrared light, the emerald number, the right side of the main image and the silvery stripe are visible on the obverse of the banknote, while on the reverse, only the denomination and the horizontal serial number are visible.
