Coins & Bullion Bars
Investment-grade gold, verified against stamped purity and mint marks.
Investment-grade coins and bars are verified against stamped purity and mint marks, then weighed on certified scales. Sealed packaging and assay certificates are welcome but never required.
- Fast turnaround for recognized mints
- Per-piece testing for mixed lots
Stamped purity and mint marks
Recognized coins and bars carry a stamped purity figure and a mint or refiner's mark, which we cross-reference against known standards — usually faster to verify than jewelry since there's no alloy blending to account for.
Weight verification
Even with a stamped weight, we independently weigh every piece on a certified scale to confirm it matches what's printed, then test further if anything doesn't line up.
Packaging is welcome, not required
Sealed packaging, assay cards, and certificates of authenticity can speed up valuation, but removing a coin from its packaging beforehand doesn't disqualify it — we simply rely on physical testing instead.
