From the rock
Mary Anning found an almost complete skeleton and showed what these animals looked like.
Plesiosaurs were marine reptiles and only distantly related to the dinosaurs.
No human has ever seen this animal alive: the age of the dinosaurs ended 66 million years ago, and the human genus has existed for about 2.8 million years.

With the second edition of the popular Prehistoric Life series, you acquire full-value investment gold in its purest form. Each piece contains 0.5 grams of pure gold with a fineness of 999.9 – the value of this coin is based primarily on the fine gold it contains and moves with the gold price. Gold has been regarded as a proven store of value for over 6,000 years, is the world's oldest currency, and possesses an intrinsic value that has never fallen to zero. The design gives this investment its personal touch – but the true substance and reason for purchase remains the fine gold.
It is precisely the handy small format that makes this coin an attractive entry point into physical gold investment. Small amounts of gold add up over the years to a considerable fortune, can be traded worldwide, and thanks to high liquidity can be converted back into cash at any time. This places the coin among the smallest gold coins of its kind – ideal for gradual wealth accumulation and for passing on value across generations. Anyone wishing to give genuine investment gold as a gift for a personal occasion such as a birthday, christening, or wedding is not handing over a mere trinket, but a real asset of pure fine gold.
What further distinguishes this edition is its strict limitation: only 2,000 pieces were minted worldwide. This limited availability makes the coin a genuine rarity and underpins its special value appreciation potential, as steady demand is met by a strictly limited supply. Experience shows that small gold coins with such low mintages sell out quickly and are difficult to acquire afterward – a factor that further underscores the appeal of such limited editions.
The design: the Plesiosaurus from prehistoric times
The design shows the Plesiosaurus, an imposing marine reptile that roamed the ancient seas around 201 to 191 million years ago and could reach a body length of several meters. The animal glides gracefully over a seabed featuring plants and a smaller sea creature. Above the water's surface are the inscriptions "PREHISTORIC LIFE", "PLESIOSAURUS", "201–191 MIO YEARS BC", as well as the year of issue, 2020. Fossil remains of the Plesiosaurus were already discovered in the early 19th century by the famous British paleontologist Mary Anning – a piece of scientific history captured here in the purest gold. The reverse bears the coat of arms of the Democratic Republic of the Congo, the inscription "RÉPUBLIQUE DÉMOCRATIQUE DU CONGO", and the face value of 100 Francs, which makes the coin official legal tender of the issuing country.
The Prehistoric Life series is dedicated, edition by edition, to the fascinating creatures of Earth's history, combining a captivating theme with pure fine gold. As the second edition, the Plesiosaurus represents one of the highlights of this series. The coin is produced by the renowned German mint B.H. Mayer, known for its exceptionally precise minting technique and the highest quality standards.
Minting quality and delivery
The Proof finish is the highest minting quality there is: mirrored surfaces and finely matted reliefs create an impressive sense of depth and make the design stand out in relief. Compared to simple Brilliant Uncirculated coins, production is more elaborate and the mintage significantly lower – a feature that underscores the special character of this edition. Please handle the coin only by its edges; to protect it from scratches and fingerprints, it is delivered in a sturdy coin capsule.
Gold is the world's oldest currency – it has shone for thousands of years and will not lose its shine in the future either.
