The making of the smallest gold coin in the world


 

In order to mint the smallest commemorative gold coin in the world, phases of the production process had to be adjusted. The process began with the development of the motif of the coin. In cooperation with the author, sculptor Ana Divković, we created a display of the motif detailed enough to show an entire town within a 1.99 mm diameter, yet technically feasible.

Through a special treatment, we created the smallest die for the smallest coin. The motif was engraved using Acsys’ most advanced Femto laser and their “pulse forging” technology and the smallest coin was minted on the modern automated Sack & Kiesselbach press. In case of such small dimensions, there is little space for material flow.

Therefore, adjusting the blanks for minting gave us an adequate void filing, enabling the final print. Lastly, the coins were minted one by one. After minting, the print was controlled in detail using the microscope.

“Preparation for euro coins production forced Croatian Mint to focus all strength on euro.

As a final memento, before entering the large family of the euro zone community, to proudly mark the change of currency, Croatian Mint managed to produce the smallest numismatic coin in the world:

1.99 mm in diameter, 0.05 g in weight, a 1 kuna gold coin that represents Hum, known as the smallest city in the world. “

“The starting point was reducing the motif almost to a tiny yet readable sign. The obverse shows the door handle of the entrance door to the city of Hum, in the form of the boškarin ox head, since the handle indeed is shaped in this way.

On the reverse, I dared to place the entire city to show how tiny it is. I relied on the arts and crafts of the masters at the Mint in developing this design, because Croatia is a small country of very skilful people.”

“ The greatest challenges in designing this coin were the ones invisible to the eye; the reflections of the edges of houses and the boškarin ox muscles on the reverse, which were sensed rather than seen when crafting the cast model. The most difficult of all tasks was hiding the tiny telescope within the observatory window on the obverse. Since not all stars are always visible with the naked eye, the telescope within the observatory window is also perhaps not easily seen, yet it is there, like an eye looking out into space, looking out on us.”
