20 Euro Cents 2nd map

Croatia adopted the euro on 1 January 2023, becoming the twentieth member of the eurozone — a date that required an entirely new coin series to be ready for circulation on day one. The "2nd map" reverse, used across the eurozone since 2007, replaced the original design that had shown only the fifteen pre-2004 EU member states; Croatia's own entry into the bloc came well after that map revision was already standard.

KM#139 covers the first two years of Croatian euro production, with Zagreb's HNB overseeing an initial mintage sufficient to supply a country of roughly 3.9 million people transitioning overnight from the kuna.
