In 2022, the Croatian National Bank issued the world’s smallest coin. Produced by the Croatian Mint, the gold coin has a diameter of just 1.99mm and weighs a mere 0.05 grams. It bears the motif of Hum, known as the smallest city in the world, and is part of a numismatic set in a limited series of 199 pieces, in which there is also a 1 oz gold coin with the motif of the Višnjan Observatory.
The exclusive packaging, from the Croatian studio Design Bureau Izvorka Jurić, was inspired by the desire to explore. A hard laminated box covered with dark blue paper opens like a map, leading to the valuables within. The opening process is an experience in itself. By unfolding from smaller to larger, each step reveals one part of the set, with gold text providing a guide. When fully opened, the Hum and the Višnjan Observatory gold coins are revealed on a surface illuminated by tiny LED lights, giving the impression of the night sky and helping to illuminate the coins.
The box also contains protective cotton gloves and a magnifying glass for viewing the smallest coin.
