In addition to the date of introduction of the first sentence in January 2002, the publication of figures is of increased importance because of the maximum number of banknotes received each year. The number is higher at the end of the year. The supply of euro banknotes is controlled by the European Central Bank (ECB) and the banknotes were first issued in 2002. The Europa series banknotes will be introduced gradually over several years in ascending order. The first four banknotes in the new series, the €5, €10, €20 and €50 banknotes, were put into circulation in 2013, 2014, 2015 and 2017. The Europa series will end with the issuance of the 100 and 200 euros on May 28, 2018. There will be no €500 note.

Is there a deadline and what is the exchange period for old euro banknotes? Which old euro banknotes were replaced by new euro banknotes in 2019? To date, no exchange deadline has been set for the exchange of the old euro banknotes of the first series. So, not in a hurry for that.

The first series was published in 2002 and includes seven denominations: €5, €10, €20, €50, €100, €200 and €500. The second series, the Europa series, consists of six denominations and was completed by the issuance of 100 and 200 euros on 28 May 2019. The euro was founded on 1 January 1999 when it became the currency of more than 300 million people in Europe.

As the European Central Bank plans to redesign the banknotes every seven or eight years after each issue, a second set of banknotes is already being prepared. New production and anti-counterfeiting techniques will be applied to the new banknotes, but the design will have the same theme and colours identical to the current series; Bridges and arches. However, they would still be recognizable as a new series.  On 27 January 2019, 17 of the 19 national central banks in the euro area stopped issuing €500 banknotes.
