Design and Security Features

Obverse: Most minted 100 gram gold bars display the refinery hallmark, the weight “100 g,” the fineness “999.9,” and often a unique serial number. Some manufacturers include an assayer’s signature or integrated anti-counterfeit elements such as micro-engraving or digital verification.

Reverse: Designs vary by mint and may feature a repeating logo pattern, a textured field to deter tampering, or a plain, matte finish on cast bars. Many bars ship sealed in tamper-evident assay cards listing the same serial number as the bar, supporting quick authentication.

Special features may include proprietary security technology such as surface mapping verification or optically variable elements on select issues. As investment bullion, 100 gram gold bars typically have no fixed mintage limit; production responds to market demand.

Intended Use and Market Role

Originally designed as investment units, the 100 gram gold bar serves private investors, wealth managers, and dealers who value recognized purity, portability, and liquidity. The format is widely accepted for buybacks and trading. Many bars from approved refiners meet IRS requirements for inclusion in self-directed precious metals IRAs when held by a qualified custodian. Always confirm eligibility with your custodian before purchase.

Why Choose a Secondary Market 100 Gram Gold Bar?

Secondary market bars have been previously owned and resold, often as dealer buybacks. Reputable dealers verify weight and purity and test authenticity before listing. Because production costs and packaging premiums are already absorbed, buyers often access a lower gold price per ounce compared to brand-new releases, while retaining the same metal content and recognized hallmarks.

How 100 Gram Gold Bars Are Made

Refiners produce 100 gram bars using casting or minting. Cast bars are poured and typically show a thicker profile and natural surface variations. Minted bars are cut from rolled gold strip and then stamped, resulting in crisp edges, uniform dimensions, and detailed design elements. Some refineries extrude or machine bars to achieve tight tolerances. Regardless of method, bars are weighed, assayed, and packaged to meet strict standards for fineness and accuracy.
