How to spot a counterfeit gold sovereign

The authenticity of a gold sovereign cannot be proven by one sign. Weight, dimensions, appearance, sound, and magnet tests may provide clues, but a reliable assessment requires combined inspection.
Useful indications
Compare weight and dimensions with the specifications of the particular issue. Examine relief, edges, and details. A magnet can rule out some metals, but it cannot certify authenticity on its own.
What not to do
Do not scratch, file, heat, or strike the coin. These tests can reduce value and destroy evidence needed for assessment.
FAQs
- If a magnet does not attract it, is it genuine?
- No. Lack of attraction rules out only some possibilities. It does not confirm alloy, weight, issue, or authenticity.
- Can I test it myself?
- You can make a careful visual check without altering the coin. A reliable conclusion requires combined measurements and technical inspection.
- What should I do if I am unsure?
- Keep the coin unchanged and request an assessment. Do not polish it or use tests that leave marks.
