Modern numismatic ennobling
The Multimetals effect can also be combined with other techniques used in our mint, giving the coins a distinctive character and an even more refined aesthetic.
Multimetals
noble varieties on a coin
Multimetals is an effect achieved by plating a coin with several types of precious metals. Unlike single-layer coatings, combining metals such as yellow and rose gold, ruthenium, platinum, palladium, or white rhodium creates rich contrasts and enhances the details of the relief.
Multimetals is an effect achieved through precise plating of a coin with several different precious metals. This technology involves applying selective coatings – not always in successive layers—onto a pre-prepared coin surface. This allows multiple metals to be combined within a single design while maintaining high relief readability.
The process uses:
- Yellow gold
- Rose gold
- Ruthenium
- Platinum
- Palladium
- White rhodium
Combining these metals creates distinct color and texture contrasts, allowing individual design elements to be clearly separated. The technique provides control over accent intensity and enables even very fine details to be highlighted.
Multimetals is an evolution of traditional galvanic plating, adapted to the requirements of modern numismatics. Precise masking, process control, and careful material selection give designers entirely new possibilities for creating detail and accents.
