In the world of modern numismatics, few innovations have captured the attention of collectors and designers like Smartminting®. Developed through a collaboration between CIT Coin Invest AG and B.H. Mayer’s Kunstprägeanstalt GmbH, this patented minting technology has redefined what’s possible in the striking of commemorative coins – especially in gold and silver – by allowing for unprecedented relief heights, three-dimensionality, and artistic expression.

At its core, Smartminting® is a revolution in minting technique that goes far beyond classic coin strikes. Traditional coins often feature modest relief – variations in height that create an image or portrait against a relatively flat background. Smartminting®, by contrast, makes it possible to produce ultra-high relief on both sides of a coin, achieving sculptural depth and lifelike dimensionality that were once only possible in medallic art or sculpture.

This technology has evolved since its introduction, with newer iterations such as Smartminting® 4.0 pushing relief heights to extraordinary levels. According to coin industry sources, the Iron Knight issue – the flagship example of the 4.0 generation – achieves a relief depth of up to 9 mm, far beyond what most modern minting presses have managed before, while still maintaining proof quality and intricate detail.

How Smartminting® Transforms Coins

Smartminting® works by carefully controlling the forces and die design used during the striking process. This allows the metal – whether pure silver, gold, or other precious metals – to flow into extremely deep and high areas of the design without cracking or losing fidelity. In practical terms, this means:

• Greater surface area and depth: Smartminting® can increase the visible surface and sculptural qualities of a design without necessitating a proportional increase in weight. For example, silver coins can be made larger in diameter or with oversized features yet still remain affordable for collectors.

• Creative freedom: Designers can place high points of relief anywhere on the coin’s surface – even off-center – and can combine convex and concave elements to evoke landscapes, buildings, or figures in astonishing three-dimensional detail.

• New shapes and dimensions: Smartminting® also opens the door to non-traditional coin shapes and sculptural pieces, breaking the mold of round coins and allowing for thematic artwork that stands on its own.

Together, these advancements have expanded the boundaries of what collectors expect from modern numismatic art.

Notable Coin Examples

CIT has released numerous gold and silver coins that showcase the potential of Smartminting®. Below are several standout examples, each illustrating a different aspect of the technology:

1. Tiffany Art Metropolis – San Pietro in Vaticano (5 oz Gold .9999)

This gold coin exemplifies ultra-high relief and intricate realism. The design captures the façade of St. Peter’s Basilica with astonishing clarity – right down to the miniature statues, capitals, and inscriptions. The result is more like a miniature architectural sculpture than a traditional coin.

Smartminting® allowed the recreation of the facade of Saint Peter’s Basilica in ultra-high relief on this 5 oz gold coin

2. Monuments – Leaning Tower of Pisa (5 oz Silver .9999)

Here, Smartminting® allows high relief on both sides of the coin, so that the Leaning Tower emerges dramatically from the surface. This dual-sided sculptural approach gives collectors entirely new ways to appreciate the interplay between obverse and reverse in a single piece.

3. Silver Burst 3.0 (3 oz Silver .9999)

The Silver Burst 3.0 series pairs ultra-high relief with mirror-like proof surfaces, challenging the traditional limitations of luster and texture. The reflective quality of the Polished Plate finish, combined with three-dimensional relief, creates dynamic visual effects that change with the light.

4. Topography – Grand Canyon (5 oz Silver .9999)

In this technically daring release, the Smartminting® approach is inverted: the landscape’s riverbed lies deeply recessed within the silver, creating a novel type of low relief that mimics topographical maps. It’s a bold reinterpretation of relief in coin design.

5. Scarab – Cheops (1 oz Silver .9999)

Not all Smartminting® pieces are round. The Scarab series demonstrates how flat discs can be transformed into three-dimensional, shaped works of art, offering a tactile and structural experience unlike conventional coins.

The Future of Smartminting®

As technology continues to mature, Smartminting® remains at the forefront of modern coinage innovation. Its ability to celebrate historic events, cultural icons, and artistic themes with unprecedented depth and precision makes it a favorite among numismatists worldwide. Whether in gold’s warm glow or silver’s brilliant sheen, Smartminting® coins represent a fusion of artistic vision and engineering mastery – bringing coins to life in three dimensions.
