3 Euros Blue Doctorfish

Austria's ongoing "Colourful Creatures" series uses a printing process applied directly to the coin surface rather than enamel inlay — a technique Münze Österreich developed to achieve chromatic precision that enameling cannot reliably reproduce at this diameter. The three-euro denomination itself was introduced in 2018 specifically for this series, a price-point decision designed to keep the coins accessible as collectibles while sitting outside normal circulation channels.
