Seven New Wonders of the World”, being the first spherical coin in the world that minted with unprecedented attention to detail.


This $7-face-value commemorative coin issued by Niue was struck in pure silver. The coin has a diameter of 34.00 mm. Based on the beautiful hand-drawn XVII-century map created by the eminent Dutch cartographer Willem Janszoon Blaeu, this ravishing masterpiece of monetary art combines past and present in its extraordinary design and shape – the Seven New Wonders of the World are marked on the historical map with elegant crystals.


– „The Mint of Poland continues its nearly 250-year-old tradition. Yet, our brand is considered a token of innovation. Thanks to ambitious projects and uncliched approach towards their realization, high-end technologies and highest craftsmanship, our products are pioneers in the field of numismatics.” – said Grzegorz Zambrzycki, the President and CEO of the Mint of Poland.


The Mint of Poland has taken the next step towards conquering the third dimension of the coin universe. After having successfully minted a cylinder and a pyramid, it has now added a globe to its collection. Difficulties began to show already in the design. For its generation with the ArtCAM software, the design had to be dissembled into 7 parts first. Early test runs were done with copper, but it became clear very quickly that it would not be possible to mint a very deep relief. With reliefs of more than 0.2 mm depth, you run the risk of having the metal become stuck to the die. Engraving the dies is in itself highly difficult and time-consuming: the process took 52 hours for one die only. The spherical coin was minted at 600/ 650 kilonewton on a intermediate product by using a six-partite die.


This luxurious silver coin being the example of highest craftsmanship, enraptured with its unique concept and high-end decorations! Its sophisticated design will attract even the most demanding collectors of coins!


In order to create a spherical coin, the Mint of Poland has implemented the most innovative technologies. The first stage was to prepare and evaluate a 3D-model of the coin. To assure its ideally spherical shape and map the images on it, engineers created a special 6-element die.
