Common gold myths
Biting coins, magnets, fool's gold, "gold never loses value" and more. Common myths about gold, and what is actually true.
Why gold myths spread
Gold has been prized for thousands of years, and stories have grown around it. Some myths are harmless, while others can cost people money. Here are some of the most common, with the facts.
Myths about testing gold
"Biting a coin proves it is real gold." Fact: Pure gold is soft and can show tooth marks, but so can lead and other soft metals. Modern 22K coins are hard enough that biting tells you little. It can also damage the coin and your teeth.
"If a magnet does not stick, it is gold." Fact: Gold is not magnetic, but neither are many fake metals, including tungsten, brass, copper and lead. A magnet can rule out some fakes but cannot prove gold is genuine. See how to spot fake gold.
"Real gold always looks bright yellow." Fact: Color depends on the alloy. White gold, rose gold and green gold are all real gold. See gold colors and alloys.
Myths about gold in nature
"Fool's gold is worthless." Fact: Pyrite is not gold, but it sometimes occurs alongside gold, and some pyrite contains tiny amounts of gold locked inside. Its presence can be a clue for prospectors.
"Most gold is found as nuggets." Fact: Most mined gold today comes as microscopic particles in rock. Large nuggets are rare. See largest gold nuggets.
"Gold forms on Earth." Fact: Gold was formed in extreme cosmic events, such as neutron star collisions, before Earth existed. Geological processes then concentrated it into deposits. See where gold comes from.
Myths about value
"Gold never loses value." Fact: Gold prices can fall sharply and stay low for years. There have been long periods when gold lost a large share of its value in real terms. See what moves the gold price.
"Jewelry is a good way to invest in gold." Fact: Jewelry prices include making charges and retail markups. When sold, it is usually valued at its gold weight minus refining costs. See gold in jewelry and culture.
"Collector coins are always better investments than bullion." Fact: Collector coins carry large premiums that depend on collector demand. Many buyers pay far more than they can resell for. See bid, ask and premiums.

Myths about purity and labels
"24K gold is the best for everything." Fact: 24K gold is the purest but also the softest, scratching and bending easily. Lower karats are more durable for everyday jewelry. See karats explained.
"Gold-plated items will stay gold forever." Fact: Plating is very thin and wears off with use, revealing the base metal. See plated, filled and vermeil.
"A stamp guarantees purity." Fact: Stamps can be faked. Reputable sellers and independent hallmarking systems offer stronger assurance. See hallmarks.
Myths about uses
"Spacecraft are covered in gold foil." Fact: Most golden thermal blankets are made from aluminized polyimide film. Real gold is used for specific parts, such as the James Webb telescope mirrors. See gold in space.
"There is a lot of gold in old phones, so you can get rich recycling them." Fact: Each phone contains only a tiny amount. Recovery takes industrial processes and is not worth trying at home. See gold in electronics.
How to spot a gold myth
- Be wary of claims that sound too simple, like single-step tests.
- Look for sources such as geological surveys, mints, assay offices and industry bodies.
- Remember that sellers may repeat myths to make a sale.
