Your satisfaction is our highest priority. Our goal is to educate our customers so they can make informed investments based on concrete facts. 

Whether you’re looking to add beauty and value to your coin collection or diversify your financial portfolio, we’re here to guide you every step of the way.

Let’s take an in-depth look at proof coins vs. uncirculated coins.

Both Types Are Bullion Coins

Before we dive into the factors that differentiate proof and uncirculated coins, let’s talk about what they have in common. Both types of coins are bullion coins, which are produced as a way for investors to purchase precious metals—gold, silver, platinum, or palladium.

While bullion coins offer tremendous beauty and prestige, they’re the most basic and widely available precious metal coins. Proof and uncirculated coins have premium features that make them more rare and visually appealing, and in turn, more valuable and collectible.

That said, many investors prefer bullion coins because they can be obtained for as close to the metal’s spot price as possible, minus a slight markup. When it comes to proof coins vs. uncirculated coins, you’re paying more, but you’re also getting more.

Now that you have a fundamental understanding of what bullion coins are, let’s talk about the difference between uncirculated and proof coins, and what sets them apart from standard bullion coins.

Proof Coins: The Best of the Best

Simply put, proof coins are the premier bullion coins offered by their respective governments. While they’re technically bullion coins, their superior design and manufacturing elements put them in the category of rare, highly collectible numismatics, as well.

What does the term “proof” mean, anyway? It refers to a very special, meticulous minting process. When comparing proof coins vs. uncirculated coins, you’ll find that both offer breathtaking eye appeal, but proof coins are especially stunning. 

Here’s how they’re made by the U.S. Mint:

  • The proof blanks are cleaned, polished, and treated by hand to ensure the highest quality strikes.
  • The hand-processed blanks are hand-loaded into presses that are outfitted with polished dies.
  • The coins are struck multiple times (at least twice).
  • The coins are packaged in a commemorative protective capsule and include a Certificate of Authenticity.

This painstaking process results in breathtaking finishes. The intricate imagery is highly detailed with no blemishes, the foreground is beautifully sculpted with a softly frosted appearance, and the background has a brilliant luster and mirror-like shine.

Uncirculated Coins: A Step Above Bullion Coins

When comparing proof vs. uncirculated and bullion coins, it’s worth noting that standard bullion coins are usually technically uncirculated (as long as you buy them new), as they haven’t changed hands or been used in commerce. 

However, in this context, the term “uncirculated” refers to a specific type of coin. The primary difference between uncirculated and proof coins is the minting process. 

Uncirculated coins are produced the same way as standard bullion coins and everyday coins used for currency, but with additional special processes that give them an exceptionally brilliant finish. Whether you prefer the look of proof coins or uncirculated coins is a matter of preference.

Here’s how they’re made by the U.S. Mint:

  • Specially burnished blanks are hand-loaded into presses that are outfitted with fresh dies.
  • The blanks are struck only once, but with a higher amount of force.
  • The coins are then polished and plated to give them a finish that’s soft and matte-like, yet with a brilliant shine.
  • The coins are packaged and include a Certificate of Authenticity.

Which Coin Is Right for You?

If your goal is simply to own precious metals, standard bullion coins will suffice. However, if you’re interested in collector’s pieces, it’s time to weigh the pros and cons of proof coins vs. uncirculated coins.

Proof coins cost more, but there’s a high probability that they’ll be worth more in the future due to their scarcity, as long as you store them with care to prevent damage. Uncirculated coins are also rare and have the potential to grow in value, but they’re more widely available.

Besides speculating about future value, consider liquidity. If you decide you want to sell your coins, it may be more difficult to find a buyer for proof coins due to their higher value. In comparison, uncirculated coins are more ubiquitous and affordable, so finding a buyer should be relatively easy.

As you compare proof coins vs. uncirculated coins, remember that either way, you’re purchasing a collector’s piece.
