The coin features a design based on a 1638 hand-drawn world map, Nova totius terrarum orbis geographica ac hydrographica tabula, created by eminent Dutch cartographer Willem Janszoon Blaeu. The map is in the collection of the Boston Public Library.
At different positions on the design’s historical map are seven Swarovski crystals, one for each of the Seven New Wonders of the World. The ”wonders” were announced July 7, 2007, after a global contest to select them.
The list features Chichen Itza (Mexico), Christ the Redeemer statue (Brazil), the Great Wall of China, Machu Picchu (Peru), the ancient city of Petra (Jordan), the Taj Mahal (India), and the Roman Colosseum (Italy).
To create a spherical coin, the Mint of Poland first prepared and evaluated a three-dimensional-model of the coin using Delcam’s modeling software ArtCAM. To assure the coin’s ideal spherical shape and map the images, engineers created a special six-piece die setup, with hammer (top) and anvil (bottom) dies joined with four collar dies on the sides.
The Mint of Poland developed multiple strategies and technologies to strike the coin, which has thus far been a “one-off” issue (i.e., no other globular coins have been issued).
The world of coins depicting maps and shaped like maps continues to evolve, and the options are only increasing. Now might be the perfect time to chart a new course forward in your collecting journey.
