The first of the coin additions is actually the third in the ‘To Protect’ series, looking at famous military helmets from history. The first issue was a 16th century Burgonet cavalry helmet, followed last year by a very neat Japanese helmet from the 17th century, that the Asian country had based around a European type. For 2024, we have the legendary winged helmet, worn by the Polish Hussars.

It’s the same two-ounce silver format, with high-relief, and selective gilding. The background is a battle scene, and the obverse has a unique to each release patterned design. An attractive range, sporting unusual historical subjects, they come boxed in a display frame, with an enclosed Certificate of Authenticity.

Finally, we have the follow-on coin to the Tyrannosaurus Rex release from early 2022. This one takes a bit of explaining. There are a pair of two-ounce coins in the set, which share a common obverse (the footprint design below). The two coins have a different reverse face, and those are what makes this stackable. They are not infinitely so, like the bullion range, but only stackable as a pair, with one depicting the fossilised skull, and the other a look at the living creature.

As we said, this is only available as a set with both coins in, and it’s fully denominated for the Republic of Chad. The relatively tiny mintage of 250 sets puts any pretence at being bullion firmly to bed. Something a bit different in what is one of the most packed genres in modern coins.
