50 Euro Cents 1st type, 2nd map

San Marino's euro coinage is struck under a formal agreement with the European Union — the republic is not an EU member but has used the euro since 2002 under a treaty that grants it a strict annual mintage ceiling and requires all designs to be approved by Brussels. The "2nd map" reverse, introduced across the eurozone in 2007, updated the geographic depiction to include Cyprus and Malta following their 2004 EU accession.

San Marino's pieces are minted by the Istituto Poligrafico e Zecca dello Stato in Rome, not on Sammarinese soil.
