A 2012 Manhattan dealer discovered ten tungsten-cored 10 oz gold bars in his inventory — over $180,000 in counterfeits that had passed his initial screening. In 2017, a gold bar certified by the Royal Canadian Mint turned out to contain a tungsten core. On AliExpress right now, you can buy a fake American Silver Eagle for $1.50 shipped. The counterfeit precious metals problem is industrial in scale, and the fakes are getting better every year. This site documents the problem and teaches you how to protect yourself.
The most commonly counterfeited investment coins — exact specs, specific tells, and the tests that actually catch fakes.
The most counterfeited silver coin in the world. Real ones weigh 31.103g with exactly 198 edge reeds. Fakes come in light at 30.2–30.8g and the torch hand detail is always mushy.
Post-2014 Maples have radial lines and a micro-engraved privy mark that fakes cannot replicate. Tilt the coin under a light — no shimmer means no sale.
The 22kt copper alloy gives genuine Krugerrands a rose-gold colour that fakes never match. Check the Springbok horns — they should be banded and thick, not thin and plain.
The 2021 redesign added four security features including surface animation using picosecond lasers. No counterfeiter has cracked it yet. Pre-2021 coins are more vulnerable.
Annual design changes make Pandas uniquely hard to authenticate from memory. Real ones show mirror-finish black fur and frosted white fur. Fakes lack this contrast entirely.
Perth Mint coins dated 2016+ have a micro-engraved letter visible only under a loupe. Fakes are consistently thicker than genuine coins and come in underweight.
Counterfeit bullion bars are a massive problem — tungsten has 99.64% of gold's density, making it the perfect core for fakes that pass a scale test.
Tungsten costs $30–$50 per kilo. Gold costs $75,000+. A $15 tungsten blank with gold plating sells for $2,000 as a fake 1 oz bar. Only ultrasound and Sigma testing catch these reliably.
The most counterfeited gold bar product in the world. Fakes now come in packaging so close to genuine that the assay card swooping line touching the first "P" is a tell. Use Veriscan.
Engelhard stopped production in 1988, turning every bar into a collectible with 20–100% premiums. Cross-reference serial numbers against AllEngelhard.com — fake formats are well-documented.
JM exited retail bullion in 1999. Counterfeits often lack stamped serial numbers or have laser-etched numbers instead. Copper-core fakes are thicker than genuine — measure with calipers.
Numismatic counterfeits target the collector premium — a $2 fake 1893-S Morgan sold as a $5,000 rarity.
One inherited "collection" of 122 coins was entirely counterfeit. Key dates like the 1893-S and 1889-CC are faked with die-struck methods and even sold in fake PCGS slabs.
The 1928 Philadelphia (360,649 mintage) is the most counterfeited. Some fakes pair a 1928 obverse with a 1921 reverse — the counterfeiter used the wrong reference coin entirely.
Lebanese fake 1917 Sovereigns fooled dealers for decades. The horse's tail detail and the "pimply" surface texture are now-documented tells. Chinese fakes have taken over since 2010.
Conservative estimates: 30–40% of ancient coins sold online are fake. Over 50% on eBay. Cast fakes show telltale porosity under 10x magnification that struck coins never have.
Nine methods ranked from free to $1,000. A $15 scale, $10 calipers, and the free Pingcoin app will catch 99% of counterfeits. Here is exactly how to use each one.
Measures electrical resistivity through plastic, capsules, and slabs. Tungsten reads 5.65 vs gold's 2.44 — a 2.3x difference the Sigma catches every time. Worth it if you hold $5K+ in metals.
APMEX, JM Bullion, SD Bullion, and Monument Metals reviewed. What to look for in a local coin shop. Why eBay sellers under 99.5% feedback are a gamble.
18 USC 485: up to 15 years for counterfeiting US coins. The Hobby Protection Act requires "COPY" marking. A Florida man got 30 months for reselling AliExpress fakes on eBay.
Search "silver eagle replica" on AliExpress: hundreds of listings at $1.50–$5 each. Minimum orders of 500 pieces on Alibaba. The supply chain from Shenzhen factory to your eBay purchase.
NGC and PCGS reject thousands of counterfeits submitted for grading annually — and those are just the ones that reach grading services. Industry estimates: 5–15% of secondary-market Silver Eagles are fake.
A genuine Silver Eagle rings at 5,900–6,300 Hz for 3–5 seconds. A steel-core fake dies in under half a second at 8,000–12,000 Hz. Free apps like Pingcoin measure the difference precisely.
Silver's SG of 10.49 sits in a gap no cheap metal matches. A $15 scale and a cup of water will definitively catch copper-core fakes (SG 8.96). Step-by-step instructions with worked examples.
Density difference: 0.36%. Electrical resistivity difference: 116%. That is why a $15 scale cannot catch tungsten fakes but a $700 Sigma verifier can. Full technical breakdown.
Gold Philharmonics have reeded edges with incuse lettering. Silver Philharmonics have smooth edges. A fake with a plain reeded edge and no text is always counterfeit. Check the edge first.
The headdress feathers and buffalo shoulder fur are where every counterfeit fails. Genuine feathers show individual rachis and barbs under magnification. Fake feathers are smooth paddles.
