Explore the mysteries of the universe with the Austria 2025 Silver Niobium - Quantum Physics 90% Silver Coin 16.5g, an innovative release from Münze Österreich that bridges advanced science with cutting-edge minting artistry.

Struck from 16.5 grams of 90% pure silver with a coloured niobium core, this 16.5g coin showcases a striking two-tone design created through a unique oxidation process—resulting in vivid, permanent colouration without the use of paint or coating.

The reverse celebrates quantum entanglement, inspired by the groundbreaking experiments of Nobel laureate Anton Zeilinger. It depicts the simplified experimental setup involving ALICE (A) and BOB (B), connected through quantum and classical channels. The niobium core visually represents two entangled particles with opposing spins, capturing one of the most fascinating phenomena in modern physics. The reverse includes inscriptions “QUANTENPHYSIK” and “QUANTEN KANAL”. The obverse features the iconic Schrödinger’s cat thought experiment, a powerful symbol of quantum superposition. The cat’s expression reflects the duality of existence, both ‘alive’ and ‘dead’, while surrounding elements, such as an unstable atom, a Geiger counter scale, a radioactivity symbol, and an observer, illustrate the probabilistic nature of quantum reality. The abbreviated form of Schrödinger’s equation appears at the top, reinforcing the scientific theme. The obverse includes the country of issue, face value and year of issue.

This coin is part of Austria’s renowned Silver Niobium series, known for its patented technology and distinctive colour contrasts. Presented in Special Uncirculated quality, it comes housed in an official display case with a Certificate of Authenticity. With its fusion of science, art, and innovation, this coin is an exceptional collectible for enthusiasts of physics, technology, and modern numismatics.
