5 Euros Campanula Saxatilis

Part of the Bank of Greece's ongoing native flora series, this issue belongs to a collector-focused program begun in the 2010s documenting endangered or regionally significant plant species. Campanula saxatilis, the rock bellflower, grows almost exclusively on the limestone cliffs of Crete — a distribution so narrow it has earned protected status under Greek environmental law. The .333 fineness places it at the lower threshold of what most markets classify as silver coinage, a deliberate cost-containment choice that kept the series accessible to domestic collectors rather than bullion-oriented buyers.
