20 Euros Widnet il-Baħar coinbar

The "Widnet il-Baħar" — Maltese for sea lavender, the low-growing halophyte endemic to the Maltese islands' coastal salt marshes — is one of a small cluster of species that the Maltese government has placed under strict legal protection due to habitat loss along the island's increasingly developed shoreline. This coinbar format, a hybrid product sitting between bullion and numismatics, has become a favored vehicle for the Central Bank of Malta's higher-weight silver issues, allowing 500g of .999 silver to carry legal tender status without the production constraints of a conventional round flan.
