Austria 3 Euro 2023 " Swell Shark" UNC

The swell shark gets its name from its ability to inflate itself to roughly double its normal size by swallowing water as a form of protection from predators.

But that’s not its only amazing property – the hero of the second coin in the Luminous Marine Life series can also fluoresce green all over.

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 wide band, reminiscent of an old-fashioned porthole frames the aquatic scene on the coin’s reverse.

A swell shark appears to swim through the porthole, its body brown in colour when illuminated with ultraviolet light glows green. As on all coins in the series, to the left and below a shell and a starfish can be seen.
