Government Mints vs Private Mints
Gold bars are produced by sovereign mints and private refineries. Most gold bullion bars are produced by well-known private mints such as Valcambi and Argor-Heraeus, recognized worldwide for their quality and precision.
At the same time, respected government mints like the Royal Canadian Mint, the Perth Mint, and the Royal Mint also produce gold bars, often backed by strong reputations and strict standards.
You may also come across gold rounds, which are similar in purity but shaped like coins. These are typically made by private mints and do not carry a face value, making them a popular and affordable option.
What to Look for in a Gold Bar
When buying physical gold bars, a few key factors can help you choose the right product and protect your investment:
1. Trusted Mint - Always check who produced the gold bar. The mint’s name or logo is typically stamped on the bar, making it easy to identify.
2. Reputation Matters - Gold bars from recognized mints are easier to sell worldwide and may command better resale prices.
3. Gold Purity - Investment-grade gold bars should contain at least .999 fine gold, ensuring global acceptance.
4. Assay and Authentication - Most gold bars include proof of authenticity, such as an assay card or engraved markings with weight and purity. Some even include exclusive serial numbers to enhance secutiry.
Types of Gold Bars
Gold bars are produced using different methods, which can affect their appearance, premiums, and overall appeal to investors. The two main types are cast gold bars and minted gold bars.
Cast Gold Bars
Cast gold bars are made by a simple process of pouring molten gold into a mold and allowing it to cool naturally (or dropped into cold water). This creates a rugged, hand-poured look with lower premiums, making them ideal for value-focused investors.
Minted Gold Bars
Minted gold bars are produced by cutting and stamping gold sheets into precise shapes. They have a smooth, polished finish and are often sealed in assay packaging.

How the Spot Price Affects Gold Bar Prices
Gold bar prices are based on the live spot price of gold, which fluctuates throughout the day in response to global market activity (e.g. LBMA - London Bullion Market Association and COMEX - Commodity Exchange Inc.) The spot price represents the base value of gold but does not include dealer costs.
Dealers add a premium to cover refining, manufacturing, and distribution. Larger bars typically have lower premiums per ounce, while smaller ones cost slightly more per ounce, though they are a more manageable size.

FAQs
Are Gold Bars as pure as Gold Coins?
Most gold bars and gold coins are made from .999 or .9999 fine gold. The format itself does not determine purity. Instead, purity depends on how the gold is refined and whether alloys are added. In general, both meet strict investment-grade standards, making them equally reliable for investors seeking high-purity physical gold.
Why are gold bars less expensive than gold coins?
Gold bars are typically produced by private mints, whereas gold coins by sovereign mints. Therefore, gold coins enjoy legal tender status and a face value. Their purity and authenticity is certified by the issuing government. Additionally, counterfeiting legal tender coins usually comes with greater criminal punishment than regular gold bars. Finally, the minting process involved in the making of the intricate designs of gold coins tends to command higher premiums than gold bars.Is one gold bar better than another?
What determines the intrinsic value of a gold bar is its weight and purity. However, some brands are more recognizable than others. Thus, it might be easier to resell a gold bar from a prominent mint than from a less popular one.Why do Gold bars generally sell back for less than gold coins?
Gold coins carry legal tender status and are guaranteed by a sovereign government. As a result, they tend to be more liquid than gold bars. That translates to more affordable premiums for gold bars than for gold coins, including when selling them back.How do gold bars come packaged?
Gold bars come in different packaging types depending on the manufacturer. Many smaller bars are sealed in tamper-evident assay cards that list weight and purity. Larger bars may be shipped in protective plastic, boxes, or sleeves. Packaging helps protect the bar and verify authenticity, so always check the product details before purchasing.
What is an Assay?
An assay is a test or analysis performed to determine the purity, composition, and quality of precious metals such as gold and silver, or platinum. For bullion products like bars and coins, an assay certifies the metal's weight and purity, ensuring its authenticity. Often, gold bars come with an assay card, which includes details like the assayer's stamp, weight, and the purity of the metal, giving buyers the peace of mind that they are investing in an authentic product.How do you pronounce Assay?
In American English it is pronounced /æsˈeɪ/, with the stress in the first syllable, and the first “a” pronounced as in “apple”. In British English it is pronounced /əˈseɪ/. The stress is in the second syllable and the first “a” is pronounced like /uh/ (as in “again”).Are there any anti counterfeit properties in gold bars?
Gold bars often include anti-counterfeit features to ensure authenticity, such as holograms, unique serial numbers, tamper-evident assay cards, and micro-engraving. Some bars also come with QR codes for online verification. The best way to avoid buying counterfeit bars is to shop for prominent mints and from respectable dealers only.Do bars in Assay buy back at a higher premium than loose bars?
Yes, gold bars in assay often buy back at a higher premium than loose bars. The assay card certifies the bar’s authenticity, weight, and purity, serving as an anti-counterfeit measure. Bars in assay are generally considered more trustworthy and easier to resell. Consequently, buyers and dealers may be willing to pay a slight premium for bars that remain sealed in their original assay packaging.Is a troy oz the same as a regular oz?
No. A Troy oz is a unit of measure specifically used in the precious metals industry for centuries. It is approximately 10% heavier than a regular oz. The regular ounce, also called avoirdupois ounce, is equivalent to 28.35 grams, whereas a Troy ounce is equivalent to approximately 31.1 grams.What are the Pros/Cons to buying smaller or larger gold bars vs the standard 1 oz bar?
Larger gold bars tend to carry lower premium percentages than smaller bars. In other words, you are able to buy more pure gold bullion content per dollar invested. However, smaller bars are more affordable, easier to transport and store, and tend to be more liquid than larger ones. Nevertheless, bullion bars overall tend to carry lower premiums compared to bullion coins, such as the Silver American Eagle, or Gold American Eagle.Can you buy gold bars at a bank?
Yes, some banks, particularly in countries like Switzerland, Canada, and certain European nations, do sell gold bars. However, in the U.S., it is less common for banks to offer gold bars. Instead, most buyers purchase gold bars from specialized bullion dealers, precious metal exchanges, or online retailers, such as SD Bullion. Make sure to shop only from respectful dealers to assure you are purchasing authentic gold bars.Are gold bars worth buying?
Gold has been used as a store of value for generations. In this fiat currency era, many investors turn to gold in times of economic crisis to hedge against inflation and protect their purchasing power. Gold tends to perform opposite to fiat currencies. For instance, any time the US Dollar is underperforming, you can expect gold prices to rise.How much is a gold bar worth?
A gold bar is priced based on the current gold spot price plus a premium charged by dealers (a markup). The gold spot price fluctuates during the day based on live transactions occurring on mercantile markets, such as COMEX and NYMEX. Thus, a gold bar will be worth the live spot price.How do I verify the authenticity of a gold bar?
LBMA accredited refineries will stamp their gold bars with hallmarks, which are indications of weight, purity and usually a serial number. Additionally, most gold bars come with an assayer's mark, attesting to the product’s authenticity. Some gold bars may be accompanied by a Certificate of Authenticity or an Assay card as well. Ultimately, you can take your bars to a bullion expert for verification. However, the best way to guarantee you are purchasing authentic gold bars is to shop from respected dealers only, such as SD Bullion.What factors influence the price of gold bars?
Mainly two factors influence the price of gold bars: the gold spot price, which is a live index that fluctuates during the day according to deals occurring on mercantile markets, such as COMEX and NYMEX; and premiums, which are markup percentages that bullion dealers charge over the gold spot price to cover business costs and obtain a profit. In the long run, the spot gold price rises or falls according to supply and demand, which, in turn, is affected by several factors, including macroeconomic instability, geopolitical frictions, inflation, interest rates, the strength of the US Dollar, and others.Are gold bars a good hedge against inflation?
Yes. Gold bars are a store of value that help you protect your purchasing power against inflation and fiat currency devaluation. As a hard asset that has been valued by millennia, gold is also a portfolio diversifier.Can I add gold bars to my retirement account (IRA)?
Yes, you can. You need a self-directed retirement plan. Additionally, your gold bar must be held by an authorized custodian. To be approved in a precious metals IRA, gold bars must be 99.5% pure.What are the tax implications of buying or selling gold bars?
In the United States, the Internal Revenue Service (IRS) classifies gold bars as collectibles. When you sell gold bars that you’ve held for more than a year, the profit is subject to long-term capital gains tax, with a maximum rate of 28%. If you sell within a year, any gains are taxed as ordinary income, according to your income tax bracket. It is important to consult with a tax specialist to understand the specific tax implications of buying or selling gold bars in your country or region.What documentation should I receive when buying gold bars?
That depends on the gold bar. Some are shipped without certification, while others carry a Certificate of Authenticity, or an Assay Card. Please consult the description on the product’s page for more information, or contact our customer support at 1(800)294-8732.Can I buy fractional gold bars?
Yes, you can. There are different size options of gold bars available for purchase here at SD Bullion to accommodate any budget. You can buy from small 1 gram gold bars to larger bars. Fractional gold bars include gram gold bars, and any fractional weight of 1 oz, such as 1/2 oz, 1/4 oz and 1/10 oz.What happens if I lose the assay card or certification that comes with the gold bar?
Gold bars with an assay card or certification tend to sell back at slightly higher premiums than the ones without them. The authenticity of your gold bars can still be attested by different tests bullion dealers can take to make sure they are purchasing a legitimate gold bar. However, you might receive a smaller offer than you would if you still had the assay card or certification.
