Top 10 Facts About Gold

By Peter Reagan Reviewed by Phillip Patrick Last updated on 7/28/26 Share

There are several facts about gold you might not know about, such as its high conductivity that makes it an essential component  in smartphones and computers to the fact that it’s edible. Whether you're curious about its unique physical properties or considering investing in gold, these fun facts about gold will probably surprise you. And, we hope, give you a deeper appreciation for this remarkable element. 

1. Gold Has Many Uses

One of the most interesting facts about gold is its incredible versatility across multiple industries. While gold is primarily thought of as either jewelry or a physical asset for investment, there’s more. This precious metal serves a number of surprising purposes in today’s world.

The electronics industry uses gold extensively because of two unusual properties: 

1. Gold doesn't corrode and conducts electricity exceptionally well – though not quite as well as silver and copper.¹
2. Gold does not oxidize or tarnish over time (that’s what makes it a “noble metal”), so its conductivity remains stable even over long periods.

This combination of high conductivity and corrosion resistance makes gold crucial for high-performance, critical circuits. That’s why gold can be found in smartphones, computers, and printed circuit boards of all kinds.²

Computer manufacturers use gold-plated connectors and circuit boards because gold maintains its conductivity even when exposed to moisture and air. This reliability is why you'll find gold in everything from high-end audio equipment to medical devices, where failure isn't an option.

Medical professionals use gold in dental work and certain treatments like radiation therapy and arthritis treatment because it's virtually chemically inert and won't cause allergic reactions or immune responses in most people. Specifically, gold is used to plate stents that support weak arteries, pacemakers and other implanted medical devices.³

2. Gold Has Been Valuable for Thousands of Years

Gold facts often center on its rich historical significance. Ancient civilizations recognized gold's value long before modern economics existed. One of the oldest surviving texts, the Code of Hammurabi (1770 B.C.) references gold specifically as a means of payment.⁴

As far back as 3100 B.C. Menes, the founder of the first Egyptian dynasty, codified gold as a form of money.⁵ The Egyptians mined gold, using it to create elaborate burial masks and jewelry for pharaohs and other important citizens.⁶

The ancient Greeks and Romans viewed gold as a symbol of the gods, with many mythological stories revolving around golden objects. The war between the ancient Greeks and the city of Troy started because three goddesses each wanted to be awarded a golden apple. Jason and the Argonauts went on adventures to The ancient Greeks and Romans viewed gold as a symbol of the gods, with many mythological stories revolving around golden objects. The war between the ancient Greeks and the city of Troy started because three goddesses each wanted to be awarded a golden apple. Jason and the Argonauts went on adventures to recover the famous golden fleece. In the ancient Americas, Aztec and Maya cultures prized gold as a symbol of the sun (for its reflectivity) and of immortality (for its corrosion resistance).⁷ The first known coined money, the Lydian stater minted in the 6th century B.C. was made of gold, silver and electrum (a naturally-occurring alloy of gold and silver).⁸

Throughout history, gold has served as currency, a symbol of wealth and a store of value that transcended cultural boundaries. This historical significance continues today. Unlike paper currencies that can lose value due to inflation or political instability, gold has maintained its purchasing power over centuries.

3. Gold is the Most Malleable and Ductile Metal

Among all the interesting facts about gold that showcase its unique properties, gold is both the most malleable and ductile of metals. Malleability refers to a material property to deform under compressive stress, allowing it to be hammered or rolled into thin sheets without breaking. A single ounce of gold can be turned into a sheet covering 300 square feet, thin enough that light can pass through it.⁹

This extreme malleability allows jewelers to create intricate designs and detailed work that would be impossible with other metals. Gold's ductility is equally impressive. Ductility refers to a material’s ability to stretch, bend or be drawn into thin wires without fracturing. You could stretch one ounce of gold into a wire 50 miles long without it breaking.¹⁰ From delicate electronic components to artistic creations, gold's workability sets it apart from other precious metals.

4. Gold Has a High Boiling Point

Here's one of the most surprising facts about gold that most people don't know: gold has an extremely high boiling point of 5084.6 degrees Fahrenheit (2,807 degrees Celsius).¹¹ This means gold remains solid under conditions that would vaporize many other materials.

Fun gold fact: Did you ever wonder why we call some forms of the metal “gold bullion” and some forms of soup are called “bouillon”? It turns out that both terms come from the same Old French root, boillon, referring to the froth on top of a boiling cauldron. Bullion is for investment; bouillon is for eating.

5. Gold Is an Excellent Conductor of Heat and Electricity

Gold's excellent conductivity properties make it indispensable in modern technology. While both copper and silver conduct electricity better, gold is the #3 best electrical conductor among the metals. As we’ve discussed, gold's resistance to corrosion gives it a significant advantage in electronic applications where long-term reliability matters.

The thermal conductivity of gold also makes it useful in specialized applications where heat transfer is critical, such as in certain industrial processes and advanced cooling systems. 

Again, gold is not the best thermal conductor among metals (both silver and copper outrank it), but its corrosion resistance more than makes up the difference in critical applications. For example, gold plays a crucial role in aerospace technology, where its resistance to corrosion and radiation makes it invaluable for satellite components and space equipment. Satellites often have gold-plated solar panels, antennae and other external surfaces (America’s first astronauts even wore helmets with gold-plated visors for glare protection.^{12, 13}

For investors interested in buying gold bullion, this property provides additional assurance that their investment will retain its physical integrity over time.

6. The Most Expensive Gold Coin Sold for $18.9 Million

One of the most fascinating fun facts about gold involves a record-breaking auction sale. In 2021, a single 1933 Saint-Gaudens Double Eagle gold coin sold for an astounding $18.9 million.¹⁴

This sale demonstrates how gold's value extends beyond its metal content when combined with rarity and historical significance. For collectors and investors, it shows how precious metals prices can reflect much more than just the underlying commodity value.

Australia’s Perth Mint created the world’s largest gold coin in 2011. The one-ton Kangaroo, weighing 2,231 lbs, is on permanent display at the Perth Mint’s Gold Exhibition.¹⁵ If ever offered for sale, this massive Australian gold coin’s melt price alone would easily eclipse the Saint-Gaudens coin.

7. You Can Eat Gold

Here's one of the more unusual and interesting facts about gold: it's completely safe to eat. Edible gold, typically in the form of ultra-thin flakes or powder, appears in high-end restaurants and luxury foods around the world. Chefs use edible gold to add visual appeal to desserts, cocktails, and gourmet dishes, though it adds no flavor. For those of us who don’t frequent high-end restaurants run by gourmet chefs, edible gold is frequently consumed in the form of Goldschläger, the Swiss cinnamon schnapps. (Yes, that’s real gold leaf floating in the bottle! But not very much, only 10-13 milligrams or 0.0003 troy oz.)

8. The Deepest Gold Mine in the World is 2.5 Miles Deep

A mine in South Africa holds the record as the world's deepest gold mine, extending approximately 2.5 miles (4 kilometers) below the Earth's surface. Working at such depths presents enormous challenges, including extreme heat and pressure.¹⁶

Temperatures at the bottom of the mine can reach 140 degrees Fahrenheit, requiring sophisticated cooling systems to make working conditions bearable.¹⁷

These conditions are increasingly becoming the norm, though, as the majority of the world’s easily-accessible gold has already been mined.

9. The Gold Standard Used to be the Basis for the World's Currencies

From the late 1800s through the early 1970s, most major currencies were backed by gold reserves. At first that meant currency or “gold notes” could theoretically be exchanged for a fixed amount of gold. The convertibility of currency into gold was suspended for U.S. citizens in 1933, but other nations could still exchange their dollar reserves for gold bullion at $35/oz.

The United States abandoned the gold standard in 1971 under President Nixon, ending the direct convertibility of dollars into gold in order to preserve the remnants of the U.S. gold reserve. This shift to unbacked currencies worldwide altered how governments manage monetary policy. The monetary role of gold in the global economy declined.

Despite no longer backing currencies directly, gold remains important to central banks worldwide. Almost every country still holds significant central bank gold reserves as part of their monetary policy strategy, recognizing gold's unique role as a politically-neutral store of value and hedge against inflation.

10. The U.S. Federal Reserve Holds More than 260 Million Troy Ounces of Gold

The United States maintains the world's largest gold reserve, with the U.S. Treasury owning more than 260 million troy ounces of gold.¹⁷ Despite that impressive amount, the current 8,133-ton U.S. gold reserve is just a fraction of the more than 20,000 tons the U.S. held at the end of World War II (more than ⅔ of the world’s official gold!)

Although most people have heard of the U.S. Bullion Depository at Fort Knox, most don’t realize that legendary location with its 5,000 tons isn’t even the biggest gold hoard in the U.S. 

The Federal Reserve Bank of New York in Manhattan stores 6,331 tons of gold in its three-story vault 80 feet below street level. The majority (90%) of this gold is owned by foreign nations, central banks and international organizations (not the U.S. government). The vault, built directly into Manhattan's bedrock and protected by a 140-ton steel-and-concrete frame, is secured by a 90-ton steel cylinder entryway.¹⁸

Even though the world no longer uses the gold standard, maintaining these reserves provides a layer of financial credibility and optionality. A tangible asset independent of the dollar system, that can’t be “printed” into existence. This matters particularly in times of economic stress, when gold’s role as a universally recognized store of value becomes more important.

For individual investors considering a precious metals IRA, the fact that governments continue to hold substantial gold reserves reinforces gold's role as a long-term store of value.
