Gold bar hallmarks provide important information about the product’s origin, authenticity, and quality. These markings are not just decorative—they’re functional and often necessary for resale or verification. Misunderstanding or ignoring them can lead to mistakes in value assessment.

Here’s what to look for:

• Purity stamp – Usually marked as “999.9” or similar, indicating 99.99% purity.
• Weight indication – Expressed in grams or troy ounces, depending on the refiner.
• Refiner logo or name – Reputable refiners include a consistent brand mark.
• Serial number – Unique identification helps verify authenticity and track the product.
• Assay stamp – Confirms the bar has passed verification at the production stage.

Each hallmark should appear clear and professionally engraved or embossed. Faint, misaligned, or inconsistent markings may signal a fake or altered bar. Before purchasing, compare these marks against trusted reference images or request a second opinion.
