When it comes to investing in precious metals, a gold 100g bar is one of the most popular choices for both seasoned investors and first-time buyers. Offering an ideal combination of weight, purity, and affordability, this gold bar size is widely recognized and traded across global markets.
In this article, we’ll explore why the gold 100g bar is considered a sweet spot for gold investors, what to look for when buying one, and the benefits of adding it to your portfolio.
What Is a Gold 100g Bar?
A gold 100g bar is a refined bar of gold weighing exactly 100 grams (approximately 3.215 troy ounces). These bars are typically made from 999.9 fine gold (24-karat purity) and are manufactured by trusted refineries such as:
PAMP Suisse
Valcambi
Heraeus
The Royal Mint
Perth Mint
Baird & Co
Each bar is often sealed in tamper-proof packaging and comes with an assay certificate that confirms its weight, purity, and authenticity.
Why Choose a Gold 100g Bar?
✅ Investment-Grade Gold
The 100g bar is large enough to offer meaningful investment value, while still being affordable for most serious investors. It provides a solid store of wealth that’s easier to sell or trade compared to larger bars like 1kg.
✅ Low Premiums
Compared to smaller bars (like 1g or 10g), the gold 100g bar generally comes with a lower premium over the spot price of gold, meaning you get more value for your money.
✅ Easy to Store and Transport
Its compact size makes it easy to store securely in a home safe, safety deposit box, or third-party vault. At just under the size of a smartphone, a 100g gold bar is highly portable and discreet.
✅ Highly Liquid
Because of its popularity and standardized weight, a gold 100g bar is easy to sell anywhere in the world. Whether you're in London, Dubai, Zurich, or Hong Kong, dealers will recognize and buy 100g bars from reputable mints.
