Luminous Marine Life

3 Euro Coins

From November 2022, we will be diving into the depths of the oceans with our new series, Luminous Marine Life. To celebrate the United Nations Decade of Ocean Science for Sustainable Development, we are embarking on an undersea adventure that will show just how fascinating and colourful the underwater world can be. With a mintage of 65,000, the 12 innovative 3 euro coloured coins in the series, 4 of which will be issued each year over 3 years, will not only make your eyes light up, the coins actually do that themselves thanks to special lighting effects.

As improbable and magical as the sea creatures featured on the coins may seem, they really do exist. Even though some of them live in the perpetual darkness of the deep seas, where no ray of sunlight penetrates, they all have extraordinary luminous qualities. They flash, sparkle and glow and change colour when necessary.

The same applies to the coins themselves, which glow when exposed to ultraviolet light in a way that is both exciting and piques our sense of scientific curiosity. A dedicated ultraviolet torch will help you to experience the charming creatures of Luminous Marine Life in full.

UV light effect

The series’ dedicated UV torch gives off a special type of light that appears to bring the underwater creatures on the coins to life as they change colour and glow vividly. Tiny creatures, which only become visible when you shine the UV torch on them, also appear here and there next to the main characters in the series, adding an element of surprise.

On some of the 12 coins, only the edge of a porthole can be seen, beyond which there is only emptiness and darkness. Coins on which nothing can be seen? Is that some kind of bad joke? Not at all. Shine the beam of the UV torch on the coins and you will be amazed.

Blue-ringed octopus

The blue-ringed octopus is a brilliant example of how fascinating and colourful the underwater world can be. One of the most intelligent invertebrates, this amazing animal is not only smart but also highly toxic. If it feels threatened its rings illuminate several times per second. This is exactly what it does on the first coin in the Luminous Marine Life series. You will be amazed.

Coin motif

All 12 of the magical sea creatures in the Luminous Marine Life series are shown in silhouette on the coin’s obverse. Air bubbles up between them and a tail fin disappears beneath the waves to the right.  A colour-printed blue-ringed octopus is depicted on the coin’s reverse. When the octopus is illuminated with UV light, its blue rings begin to glow and its body changes colour from yellow-brown to green. In the background swim two peacock angelfish. A wide band, reminiscent of a an old-fashioned porthole frames the aquatic scene. As on all coins in the series, to the left and below the octopus to the right a shell and a starfish can be seen.

The first coin in the fascinating Luminous Marine Life  series is both a collector coin and a great gift coin for children.
