While high-quality counterfeits exist, they are detectable with the right knowledge and tools.
Red Flags
- Price significantly below spot (too good to be true)
- Seller refuses to allow testing
- No assay card, certificate, or original packaging
- Unusual color, weight, or dimensions
- Magnetic attraction (gold is non-magnetic)
- Selling venue lacks reputation or track record
Common Counterfeit Methods
- Gold-plated tungsten: Tungsten has similar density to gold. Detected by Sigma Metalytics, ultrasound, or XRF
- Underweight copies: Counterfeiters save by using less metal. Detectable by precise weighing and measuring
- Alloy substitution: Base metals coated in gold. Detectable by acid testing or XRF
Protection Strategies
1. **Buy from established dealers** with verifiable reputations 2. **Purchase graded coins** sealed by NGC or PCGS 3. **Buy bars with assay certificates** from LBMA-accredited refiners 4. **Use a Sigma Verifier** for quick, non-destructive testing 5. **Know the specifications** — weight, diameter, and thickness should match published standards exactly
