Guaranteed Integrity
At Fibonacci Numismatics, we utilize advanced metallurgical analysis to ensure the provenance and purity of every asset that passes through our facility.
Electromagnetic Analysis
Using the Sigma Metalytics PMV, we measure the electrical resistivity of the metal. This allows us to "see" through the coin’s core to ensure it is not a gold-plated counterfeit, even if the coin is housed in a protective slab.
Acoustic Resonance
Our Acoustic Ping Test analyzes the unique frequency of precious metals. Genuine gold and silver have a distinct "ring" and sustain that base metals cannot mimic. This non-destructive test provides immediate sonic confirmation of purity.
Physical Metrics
We perform high-precision weight and dimension checks. Every asset is verified against official mint specifications using digital scales (0.01g) and calipers to ensure the density matches the intended metal perfectly.
Third-Party Certification
We facilitate submissions to the world's leading grading services, PCGS and NGC. A certified asset provides a permanent, tamper-proof record of authenticity and grade.
Our Security Protocol
Why we "Ping"
Every precious metal has a specific resonant frequency. When a 1oz Gold Maple Leaf is struck, it vibrates at a frequency that is impossible to replicate with a tungsten-core fake. Our acoustic testing captures this "fingerprint" to confirm your asset is genuine.
