Key Takeaways

Why Authentication Matters for 1000 oz Bars

With individual bars valued at $92,200+, authentication is critical for 1000 oz silver purchases. Verifying you're receiving genuine COMEX-quality product protects your investment.

The good news: COMEX-accredited bars must meet strict standards. The institutional nature of the 1000 oz market provides some protection against counterfeiting—sophisticated fakes are difficult to introduce into established channels.

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

What to Verify on 1000 oz Bars

Each 1000 oz bar should display: refiner hallmark, serial number, weight stamp (approximately 1000 oz with allowed tolerance), and purity mark (.999 fine). These markings should be clear and professionally applied.

Weight verification is important. A calibrated scale should confirm the bar weighs approximately 68-70 pounds (the exact weight varies by bar within COMEX tolerances).

Documentation should include the bar's weight certificate or assay documentation with matching serial number.

Professional Authentication

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

The cost for professional testing is modest compared to a 1000 oz bar's value. Many dealers can arrange testing or direct you to qualified services.

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