Why Authentication Matters for 100 oz Bars

With individual bars valued at $6,694+, authentication is important for 100 oz silver purchases. Verifying you're receiving genuine product protects your investment.

The good news: bars from recognized refiners have consistent markings and documentation. Dealers can authenticate them quickly. The key is buying from reputable sources in the first place.

For legitimate purchases from reputable dealers of recognized brands, authentication concerns are minimal. Risk increases when buying from unknown sources or secondary markets.

What to Verify on 100 oz Bars

Each 100 oz bar should display: refiner hallmark, serial number, weight stamp (100 oz), and purity mark (.999 fine). These markings should be clear and professionally applied.

Weight verification is straightforward. A scale should confirm the bar weighs approximately 6.8 pounds (the exact weight varies slightly by refiner within acceptable tolerances).

Documentation should include purchase records and any paperwork from the refiner. Keep all documentation for resale purposes.

Professional Authentication

For secondary market purchases or bars without complete documentation, professional authentication may be worthwhile. XRF testing verifies silver content non-destructively.

The cost for professional testing is modest compared to a 100 oz bar's value. Many dealers can arrange testing or direct you to qualified services.

When purchasing from established dealers of recognized brands, extensive authentication is typically unnecessary. These dealers stake their reputation on product authenticity.
