The uniquely shaped and coloured coins in our Uncharted Universe series were such a big hit that they all sold out on their day of issue.
This series is followed by the 20 euro silver series, The Beauty of the Universe, which again features five extraordinarily shaped and coloured coins.
Issued in May 2024, Supernova is the first coin in the series and is followed by Einstein Ring in 2025, Cat's Eye Nebula in 2026, Gravitational Wave in 2027 and Protostar in 2028

Some see coins purely as an investment. But monetary value and sentimental value are not mutually exclusive.
