20 Euros Danube Floodplains

Slovakia's silver collector series documenting domestic natural habitats has run continuously since the early 2000s, with each issue tied to a specific protected area under Slovak or EU conservation designation. The Danube floodplains along Slovakia's southern border with Hungary and Austria constitute one of Central Europe's last intact riverine forest systems, a stretch that survived largely because communist-era agricultural development stopped short of the most flood-prone zones.

KM#224 is a recent addition to a well-established run. Collector demand for the series is steady but not speculative.
