In a world of double-giant dino’s. what better than a Double Silver Giant coin? MDM returns with a fourth hybrid prehistoric coin

MDM’s ‘Double Silver Giant’ series of prehistoric animal coins returns with a fourth issue, and following superb T.Rex, Triceratops, and Stegosaurus designs, we head to the air with Pteranodon. These are similar in concept to PMC’s ‘Bi-Metal Max’ coins in having a silver skin over a far larger copper core. The end result is a large coin, and a relatively small cost for it. These 60 mm diameter, high-relief coins are usually available for around the $100/€100 mark, and look superb. The DSG series is composed of two 5-gram silver discs over a 145-gram copper core.

This Pteranodon design is, in our view, the weakest to date, mainly because this is a creature quite difficult to reproduce well on a small metal disc. However, we still love it, and consider it to be the best depiction of this flying reptile on a coin to date. The whole series has set a very high standard, and Pteranodon has little trouble keeping up. The sheer oddity of this animal comes across well.

The common obverse returns, with its parade of  eight dinosaurs surrounding the Vanuatu coat-of-arms. We originally thought that these eight would be the subjects of the coins in the series, but as Pteranodon isn’t one of them, clearly not. The silver is all antique-finished, providing a striking contrast to the polished copper on the edge, and the coin remains as attractive as its ancestors. Packaging is neat, includes a COA, and there’s a mintage of 1,999 pieces. An excellent release again, the coin is available to order now, and should ship in the next few weeks.


Pteranodon, meaning “winged and toothless,” was a remarkable prehistoric creature that lived during the Late Cretaceous period, approximately 85 to 75 million years ago. This flying reptile belonged to the pterosaur group and is often mistaken for a dinosaur, despite being a distinct branch of the archosaur family, still in existence today with the birds and the crocodilians.

Pteranodon was one of the largest pterosaurs, with a wingspan that could reach up to 30 feet (9 meters). Its most distinctive feature was its elongated crest at the back of its head, which could be as long as 6 feet (1.8 meters) in some individuals. This crest likely played a role in controlling flight and might have been used in sexual displays or thermoregulation.

Unlike its dinosaur contemporaries, Pteranodon was admirably adapted for powered flight. It had lightweight, hollow bones and a wing structure supported by a single elongated finger, which made it efficient in the air. Its diet primarily consisted of fish, and it likely spent much of its life soaring over ancient oceans, diving to catch its prey.
