Here is a first day cover from Malta dated 1 January 2008. On that day, Malta started using the Euro currency. As seen on the cover, there are two values imprinted on the postage stamp. The value in red (43 c) denotes the old currency while the value in white uses the Euro (?1).
For a period of one month until 31 January, there was a dual circulation for Malta where the Euro and Maltese lira are used alongside each other. For accounting purposes, the usage of the Maltese Lira is still allowed but limited.
To commemorate the introduction of the Euro, Malta Post issued a colourful miniature sheet featuring the coin designs. Each miniature sheet comes with a unique serial number.
