Surrounded by a plain rim, the obverse of the coin shows at its centre the Coat of Arms of the Principality of Andorra consisting of a shield divided quarterly by the arms of the Bishop of Urgell and the Count of Foix - who have historically been the two co-princes of Andorra - in addition to the emblems of Catalonia and the Viscount of Béarn.
The four traditional quarters are (clockwise from top left):
- that of the Bishopric of Urgell, represented by a mitre and a crosier (staff);
- that of Foix, with three vertical stripes;
- that of Béarn, represented by two cows with cow-bells around their necks, walking to left;
- that of Catalonia, with four vertical stripes.
The shield is surrounded by an "aureola". A scroll below it carries the Latin motto VIRTVS VNITA FORTIOR (in modern spelling: "Virtus Unita Fortior"), meaning "United virtue is stronger".
Around above, the inscription PRINCIPAT D' ANDORRA (Principality of Andorra).
Below, divided by the Coat of Arms, the value and denomination 5 D. (Five Diners).
Around below, the date of issue 2011.
