There are two series of euro banknotes in circulation.
The first series comprises seven different denominations (€5, €10, €20, €50, €100, €200 and €500). The second series, or Europa series, has the same denominations, except the €500 denomination. This denomination is no longer being printed, but it can still be used as a means of payment.
Irrespective of the series, each euro banknote denomination is visually recognisable by a dominant colour and architectural motif. The dimensions of the euro banknotes of the first and the second series of the €5, €10, €20 and €50 denomination are identical, while the dimensions of the €100 and €200 banknotes of the first and the second series differ.
