15 Euros Widnet il-Baħar coinbar

The "Widnet il-Baħar" — Maltese for the sea lavender native to the Maltese coastline — belongs to the Central Bank of Malta's ongoing nature-themed series pairing collectible coinage with environmental awareness. The coinbar format, a hybrid ingot-coin piece, has grown in popularity among European central banks since the mid-2010s as a way to attract both numismatic and bullion buyers with a single product.

At 250g of .999 silver, this sits at the heavier end of the coinbar format.
