Gold & Silver Authenticity Guide
๐ Verify Precious Metals Authenticity
Learn to identify genuine precious metals and avoid counterfeits. This guide covers at-home testing methods and professional verification techniques to protect your investments.
๐งช Quick Authenticity Assessment
๐ฌ Testing Methods Explained
๐งฒ Magnet Test
How it works: Precious metals are not magnetic. A strong magnet should not attract gold, silver, platinum, or palladium.
What you need: Strong neodymium magnet
Limitations: Some fake metals are also non-magnetic, so this test alone is not sufficient.
โ๏ธ Weight Test
How it works: Precious metals are dense. Compare the item's weight to published specifications.
What you need: Precise scale, published weight specs
Red flags: Significantly lighter (hollow/plated) or heavier (tungsten core) than expected.
๐๏ธ Visual Inspection
What to look for: Proper hallmarks, correct dimensions, quality of details, color consistency.
Red flags: Poor engraving, wrong fonts, discoloration, obvious wear through plating.
Tools: Magnifying glass, calipers, reference images
๐ Ping Test
How it works: Precious metals produce a distinctive ring when struck. Compare to known authentic items.
Best for: Silver coins and rounds
Note: Requires experience to interpret correctly. Not reliable alone.
๐งช Acid Test
How it works: Different karat acids react with metals based on purity. Genuine metals show specific reactions.
Caution: Destructive test, damages the item. Use only on inconspicuous areas.
Professional use: Best performed by experienced dealers.
๐ฑ Electronic Testing
How it works: Electronic gold testers measure conductivity to determine purity.
Advantages: Non-destructive, accurate, fast results
Cost: $100-$500 for quality units. Best for serious collectors/dealers.
๐จ Common Counterfeiting Methods
Gold Counterfeits
- Gold plating: Base metal with thin gold layer
- Tungsten core: Gold shell over tungsten (correct weight)
- Brass/copper: Similar color but different properties
- Gold-filled: Thicker gold layer but still not solid
Silver Counterfeits
- Silver plating: Base metal with silver coating
- Nickel/zinc alloys: Similar appearance, wrong properties
- Lead core: Heavy but wrong conductivity
- Aluminum: Light weight gives it away
