What Are the Purest Gold Coins? A Quick Guide for Investors

Gold is a popular choice among both novice and seasoned investors hoping to diversify their investment portfolios. When buying gold, you’ll likely discover that varying levels of purity can impact its value. So what are the purest gold coins available on the market?

Below, we discuss some facts you need to know about understanding the actual gold content and face value of popular gold coins to help you make intelligent investment decisions. If you need investment advice, we recommend speaking with your financial advisor for more information about buying gold bullion coins.

Are All Gold Coins Made of Pure Gold?

No, all gold coins contain an alloy mixture of primarily gold and other precious metals for optimal coin durability and strength. The purest gold coin in the world is 99.999% gold, which means that no 100% pure gold coins exist.

Gold coin manufacturers purchase the purest form of gold extracted from ores and molded into gold bars. During the minting process, manufacturers melt these bars to create coins. Minting companies combine the melted gold with other precious metals into a coin before stamping on the identifying symbol.

The final result typically ranges from 90 to 99.99% pure. Common precious metals used in gold coinage are silver and copper.

  • The British Sovereigns: With striking images of Queen Elizabeth II and St. George, the iconic gold Sovereign Coins offers 99.17% purity. Materialized by the Royal Mint, the spot price for this gold coin comes from its unique and matchless design.

  • South African Gold Krugerrand: The South African Krugerrand offers 90% gold with a copper alloy. In 1967, the South African Gold Krugerrand became the first gold bullion coin, weighing exactly one troy ounce. As the legal tender in South Africa, these bullion coins remain widely available and accessible to many.

Which Gold Coin Is Best for Investing?

The best gold bullion coin for investing depends on your specific financial goals. Some investors prefer the purest gold coins, which may cost more up front, though they offer optimal investment security. You can also diversify your investment portfolio with gold coins containing higher precious metal percentages that are more rare, offering intrinsic value.

Some investors also prefer gold bullion with low purchase values and high accessibility for easy trading. For example, the American Eagle gold coins are widely available and extremely popular among many investment groups.

Before investing in gold coins, we recommend considering the product’s purity, weight, purchase price, age, and rarity. The value of a 1-oz. gold coin can vary greatly from product to product, depending on many factors, so be sure to review the coin’s details. We recommend consulting your financial advisor for further investment advice.

Most Expensive and Purest Gold Coins

The most expensive gold coin in the world is the 1933 Saint-Gaudens Double Eagle. The United States minted over 455,000 of these 20-dollar gold coins in 1933, though all but 20 were melted down, making the existing coins extremely rare and sought-after.

The coin, named after the designer Augustus Saint-Gaudens, depicts Lady Liberty carrying a torch on one side in front of the Capitol Building with a soaring American eagle on the other side. With 99.9675% purity, this gold coin is relatively pure and extremely rare, allowing it to sell at auction for extreme prices.

The highest auction price for a 1933 Saint-Gaudens Double Eagle was in June 2021. A collector purchased the single coin for $18.8 million.

If you’re interested in a more accessible, less expensive gold coin from our list of options above, consider the Canadian Gold Maple Leaf or Austrian Philharmonic. While the market prices for these coins constantly fluctuate, you can typically purchase one for a few thousand dollars rather than millions.

What Is the Cheapest and Purest Gold Coin?

One of the best ways to find affordable gold coins with decent purity levels is by purchasing lighter weights. Many coins come in different weight options that you can choose between, ranging in cost.

A few options for cheaper gold coins with relatively high purity percentages include the following:

  • Canadian MapleGrams: 1-gram packs of coins with 99.99% purity
  • Chinese Gold Panda coins: options for 30, 15, and 8 grams or 1/20-ounce weights
  • Congo World’s Wildlife Bald Eagle: under $100
  • Fractional Britannia Gold Coins: available in 1/10 ounce weights

Are Rare Gold Coins Made of Pure Gold?

Like all other coins, rare gold coins are not 100% pure. Often, rare coins contain less purity than modern ones competing for the top position. What makes rare coins valuable is their limited availability.

For example, the Chinese Gold Panda, produced by the Official Mint of the People’s Republic of China, features a new design in each release, which makes every coin more valuable. A Gold Panda from last year will not look the same as this year’s series.

Some popular rare options with impressive purity levels include the following:

  • 1933 Saint-Gaudens Double Eagle
  • Chinese Gold Panda
  • Lunar Series from the Perth Mint
  • Canadian Call of the Wild

Are Ancient Coins Pure Gold?

Ancient coins also do not contain 100% gold. Like rare options, ancient coins maintain their value from historical associations and limited availability. Many collectors will pay top dollar to add ancient artifacts to their portfolios.

Popular ancient gold coins include the following:

  • Roman Nero Imperials
  • Phocaea “Female Head” Electrum
  • Coson Gold Stater
  • Constans II & Constant IV Gold Solidus
  • Nero Gold Aureus
