Monaco uses the euro through a monetary agreement and issues a small quantity of coins with national designs. Those coins have changed twice since 2002, so an older portrait is not a sign that the money has expired.
Paper money
Euro notes follow an easy architectural colour ladder - grey €5, red €10, blue €20, orange €50, green €100 and yellow €200 - wherever you spend them in Europe.
The euro banknote theme is imagined European architecture rather than real monuments: windows and gateways move from classical to modern styles, while bridges on the reverse suggest connection. Cash by Country artwork is an original, simplified interpretation and is not legal tender.
Three dates unlock the coin tray
The first series tells the handover
Prince Rainier III appears alone on EUR 2 and beside his son Albert on EUR 1. The 10, 20 and 50 cent coins carry the Prince's seal, while the copper values show the Grimaldi coat of arms.
The second series changes the sovereign
Introduced in 2006, the second series places Prince Albert II on EUR 1 and EUR 2. His monogram replaces the older seal on the middle denominations, while the Grimaldi arms remain on 1, 2 and 5 cent.
The newest portrait looks straight ahead
The third series arrived in 2025. The high values now show a frontal portrait of Albert II, making the newest EUR 1 and EUR 2 easy to distinguish from the profile used before.
Old faces still spend
The ECB lists all three series as circulating. A portrait of Rainier III or the earlier profile of Albert II is not obsolete money, and the coins remain legal tender throughout the euro area.
The notes carry no Monaco portrait
Euro banknotes use the shared European designs. Monaco's local identity lives on the national sides of the coins, so turn the change over when you want to find the principality.
