24k gold is as pure as gold gets, which is exactly why it is priced differently from everything else in the jewelry case. As I write this update in October 2026, 24k gold is worth $133.87 per gram, or $4,163.93 per troy ounce, based on the live spot price. I have been covering the gold market for more than two decades, and I still get more reader questions about 24k purity and pricing than almost any other topic, so I merged my two older guides on the subject into this single, fully updated page. Below you will find today's values, a plain-English purity breakdown, and the most popular 24k coins and bars worth considering.

How Much Is 24k Gold Worth Today?

Because 24k gold is essentially pure (99.9%+ fine), its value tracks the spot price of gold almost exactly. Take the spot price per troy ounce, divide by 31.1035 (the number of grams in a troy ounce), and you have the per-gram value. Here is what that works out to at the current spot price of $4,163.93:

Keep in mind these are melt values. When you buy a physical 24k coin or bar, you will pay a premium above spot (typically 2% to 8% depending on the product), and when you sell, a dealer will usually pay slightly below spot. If you want to run the numbers on your own pieces, my gold calculators page pulls the live spot price and does the math for any weight and purity.

What Does 24k Actually Mean? Karats Explained

The karat system measures gold purity in 24ths. A karat is simply one part out of 24, so 24k means 24 parts gold out of 24, or pure gold. Anything below that is an alloy: other metals like copper, silver, nickel, or zinc are mixed in to add hardness and durability. That is why your wedding band is probably 14k or 18k rather than 24k. Pure gold is soft enough to scratch with a coin, which makes it ideal for bullion bars and investment coins but impractical for everyday jewelry.

Here is how the common karat grades compare at today's spot price:

One tip from years of looking at hallmarks: outside the US you will often see purity stamped in fineness rather than karats. A stamp of 999 or 9999 means 24k, 916 means 22k, 750 means 18k, and 585 means 14k. If a piece is stamped with nothing at all, assume nothing and get it tested before you pay gold prices for it.

How to Tell If Gold Is Really 24k

Hallmarks are a starting point, not a guarantee. Counterfeit stamps are common on fake bars and coins, especially ones bought from marketplace sellers. The quick checks I rely on: a magnet test (gold is not magnetic, so any pull means alloy or fake), a density check (pure gold is 19.3 g/cm3, far denser than brass or tungsten-free fakes), and for anything valuable, an XRF scan at a local jeweler or coin shop, which reads purity in seconds without damaging the piece. I walk through all of these step by step in my guide on how to test gold at home. For large purchases, buy only from reputable dealers who sell products from recognized refiners, and the purity question mostly takes care of itself.

Where Is 24k Gold Traded?

The spot price that determines your 24k gold's value is set on global markets that trade around the clock. The biggest are the COMEX futures exchange in New York, the London over-the-counter market overseen by the London Bullion Market Association, the Shanghai Gold Exchange, and the Zurich bullion market. Prices flow continuously between these hubs, which is why the quote you see at 9 a.m. can differ from the one at noon. Dealers simply take that live spot price and add their premium.

What Moves the Price of 24k Gold?

Since pure gold tracks spot one-for-one, the drivers are the same ones I have watched move this market for 20+ years: real interest rates (gold tends to rise when inflation-adjusted yields fall), the strength of the US dollar, central bank buying (which has run at historically high levels since 2022, per World Gold Council data), and investor demand during periods of uncertainty. That combination is a big part of why spot gold has pushed above $4,000 per ounce in 2026. None of this means prices only go up. Gold has had multi-year flat stretches before, and anyone buying 24k bullion should think in years, not weeks.

Why Gold Has a Price Floor: Production Costs

One under-appreciated support for 24k gold values is what it costs to pull an ounce out of the ground. Miners track this as the all-in sustaining cost (AISC), and when spot prices approach it, unprofitable mines cut production, which tightens supply. The chart below shows AISC by region a few years back, when costs averaged around $1,200 per ounce:

Industry-wide AISC has climbed substantially since that chart was compiled, with the major producers now reporting costs well above $1,400 per ounce on average. Rising energy, labor, and permitting costs keep nudging that floor higher over time, which is one structural reason long-term gold bears have had a rough couple of decades.

Popular 24k Products

1. Gold coins: Many bullion coins are made of 24k (99.9%+) gold, such as the Canadian Gold Maple Leaf and Chinese Gold Panda. Note: the American Gold Eagle is popular, but it is not 24k (it’s an alloyed coin).
2. Gold bars: Gold bars are made of pure gold and are often used as an investment. 24k gold bars are available in a range of sizes, from small ones that are a few grams in weight to larger ones that weigh several ounces.
3. Gold jewelry (rare): While 24k gold is not commonly used to make jewelry because it is too soft, some pieces of jewelry, such as rings and pendants, may be made of 24k gold. These pieces are usually made as collector's items or as gifts.
4. Gold leaf: Gold leaf is very thin sheets of gold used for decorative purposes (gilding frames, statues, and sometimes even food). Gold leaf is often made from high-purity gold (commonly 22k–24k depending on the application).
5. Gold bullion: Gold bullion refers to gold that is in the form of coins or bars and is generally used as an investment. 24k gold bullion is available in a variety of shapes and sizes, and is often bought and sold based on the current market value of gold.

Gold Coins & Bars That Are 24k (99.5%+), Plus One Important Exception

The following gold coins and bars are guaranteed to be 24k or 99%+ gold, as they are produced by reputable mints like the US Mint, the Royal Canadian Mint, Credit Suisse and other trusted names.

The American Gold Eagle Coin

The American Gold Eagle is a gold bullion coin produced by the United States Mint. It was first issued in 1986 and is available in four denominations: 1 oz, 1/2 oz, 1/4 oz, and 1/10 oz. Important: the American Gold Eagle is not 24k. It is a 22-karat coin (an alloy) made for durability. However, each coin still contains the stated amount of fine gold (for example, the 1 oz version contains 1.000 troy oz of fine gold).

The front (obverse) of the coin features a design based on Augustus Saint-Gaudens' 1907 gold double eagle coin, which depicts Lady Liberty holding a torch and an olive branch. The back (reverse) of the coin features a design by Miley Busiek that shows a male bald eagle returning to his nest with an olive branch in his talons, with a female bald eagle and their hatchlings in the nest.

The American Gold Eagle is popular with collectors and investors due to its gold content and the backing of the United States government. It is also widely recognized and accepted as a form of currency. The coins are produced at the West Point Mint and are available in both uncirculated and proof versions.

The Canadian Gold Maple Leaf Coin

The Canadian Gold Maple Leaf is a gold bullion coin produced by the Royal Canadian Mint. It was first issued in 1979 and is available in four denominations: 1 oz, 1/2 oz, 1/4 oz, and 1/10 oz. Standard Gold Maple Leaf bullion coins are typically 99.99% pure (.9999). The Royal Canadian Mint has also released special issues with 99.999% purity (five nines).

The front (obverse) of the coin features a portrait of Queen Elizabeth II, while the back (reverse) features a depiction of the maple leaf, which is a symbol of Canada. The coin also includes a micro-engraved laser mark that includes the coin's weight and purity.

The Canadian Gold Maple Leaf is popular with collectors and investors due to its gold content and the backing of the Canadian government. It is widely recognized and accepted as a form of currency. The coins are produced at the Royal Canadian Mint and are available in both uncirculated and proof versions.

The Credit Suisse Gold Bar

Credit Suisse gold bars are a type of gold bullion produced by Credit Suisse, the Swiss bank that was absorbed into UBS in 2023. New bars are no longer struck under the name, which has only added to the appeal of the ones already in circulation. They are available in various sizes, including 1 oz, 10 oz, and 1 kilogram, and are made of gold that is 99.99% pure.

Unlike bullion coins who tend to have fancy designs and textures, gold bars are very basic. No fancy designs means lower production costs and lower premiums charged to the investor. Credit Suisse gold bars feature the Credit Suisse logo and the weight and purity of the bar on the front, along with a unique serial number for identification. The back of the bar is blank.

Credit Suisse gold bars are popular with large investors due to their high gold content and the reputation of Credit Suisse as a reliable and trustworthy company. They are widely recognized and accepted as a form of currency and are often used as a way to invest in gold. Credit Suisse gold bars are produced at the company's refineries and are available in both uncirculated and proof versions.

The Valcambi Gold Bar

Valcambi is a precious metals refiner based in Switzerland. The company produces a range of gold bars, including cast and minted bars in various sizes. Valcambi's gold bars are known for their high quality and purity, and are popular among investors and collectors.

Valcambi also produces the CombiBar, a unique bar that allows you to break it into small squares, like a chocolate bar. This bar is meant for those that foresee a future where gold will become currency again. Paying for day-to-day expenses with a small square broken off from your CombiBar is easier and more convenient than paying with a large 1-pound gold bar.

Valcambi gold bars are made from gold that has been refined to a purity of 99.99%, or 24k. They are available in a variety of sizes, ranging from 1 gram to 1 kilogram. The bars are individually serialized and come with a certificate of authenticity. They are also stamped with the Valcambi logo, the weight and purity of the gold, and the serial number.

Johnson Matthey Gold Bar

Johnson Matthey is a precious metals refiner and technology company based in the UK. The company has a long history dating back to the early 19th century and is known for producing high-quality gold, silver, and platinum products.

One of the most popular products produced by Johnson Matthey is a range of high-purity gold bars. These bars are made from gold that has been refined to a purity of 99.99%, or 24k. They are available in a variety of sizes, ranging from 1 gram to 1 kilogram. The bars are individually serialized and come with a certificate of authenticity. They are also stamped with the Johnson Matthey logo, the weight and purity of the gold, and the serial number.

Johnson Matthey gold bars are a popular choice among investors and collectors due to their high quality and purity. Like other gold bars, they offer a convenient and reliable way to own and store physical gold in a compact, easily transportable form. Gold is often seen as a safe haven asset, and investing in gold bars can be a way to diversify an investment portfolio and hedge against economic and political uncertainties.

Note: Did you know that you can invest in many of these products through an IRA or 401k? Many American IRA custodians will allow you to do so. In general, IRA-eligible gold bullion must meet a minimum fineness requirement (often .995+ for gold). There are also certain well-known exceptions (for example, the American Gold Eagle is commonly IRA-eligible despite being a 22k alloy). If you want to explore this option, contact one of the Gold IRA companies we reviewed to confirm eligibility for the exact product you’re considering.

We recommend that you check out Silver Gold Bull, Noble Gold or Augusta (if you have a larger budget and don't mind paying a premium for service). They have a best price guarantee on their gold bars, and claim to have some of the lowest premiums in the industry. As always, do your due diligence and shop around to find the best prices for your bullion.

It is important to be cautious when buying gold, as the market can be volatile and there are many scams and fraudulent activities that can occur. It is a good idea to research the seller and the item you are interested in purchasing to ensure that you are getting a fair price and a legitimate product. Also, please speak to your financial advisor before making any investment decision, and remember that all investments come with a certain degree of risk. Lastly, past performance isn't indicative of future returns, so invest wisely.
