The 2002 Greek 2 euro coin shows the same mosaic as every other coin minted since the country joined the euro in 2001. However, because Greece only joined the Eurozone in 2001, it could not start minting coins as early as other member states. Therefore, several coins in circulation in 2002 were not minted in Athens but in Finland, as evidenced by the 2 euro coin with the S hallmark. So some versions have an "S" in the bottom star. The S stands for Suomi, which is Finland in Finnish, as these coins were minted here and not in Athens.
