Allegiance Gold: Four Main Types of Coins

Coins fall into four main categories: Bullion, Proof, Numismatic, and Semi-Numismatic. These four types of coins differ in how they are valued and each has distinct advantages and limitations from an investment standpoint. It’s important to note that numismatic coins are not allowed to be included in a Gold or precious metals IRA; however, they continue to present a great option for investors considering investing in precious metals outside of retirement accounts.


Bullion has a recognized weight and fineness and is stamped as such. Contrary to common belief, bullion doesn’t solely come in “bricks” or bars stored in depositories. Bullion coins, made from the same precious metals, are produced annually, offering a more accessible and affordable investment option as they are smaller than entire bars.


Proof coins, with their more reflective or cameo appearance, are of higher quality and produced in limited quantities compared to bullion coins. Proof coins are among the finest quality of coins produced by the United States Mint. The term “proof” refers to the coin’s finish. Proof blanks are specially treated, hand-polished, and cleaned to ensure high-quality strikes.

The minting process of proof coins involves multiple strikes or significant pressure, resulting in enhanced details and a smoother appearance in the field area compared to standard circulated coins. Additionally, proof coins are encapsulated to maintain their quality and prevent rust, and are presented in special packaging, accompanied with a certificate of authenticity. Notably, the iconic American Eagle series offers proof versions in Gold, Silver, and Platinum, appealing to collectors and investors alike.


Numismatic coins, often older and cherished by collectors, have gained value not only for their precious metal content but also for their artistic, collectible, and historical significance. Numismatic coins must be independently certification by third-party services, which grade them and provide information about their condition and worth. Some examples of numismatic coins include the iconic $5, $10, and $20 Indian and Liberty Gold coins.

Semi-Numismatic Coins

Semi-numismatic coins combine the characteristics of both bullion and numismatic coins. Generally, semi-numismatic coins are newer bullion coins that have a limited mintage (total number produced) and are attractive to both investors and collectors alike. For instance, the Royal Canadian Mint produces special feature coins under its animal series of coins. Due to their scarcity, the value of semi-numismatic coins may surpass that of bullion over time.

A well-diversified precious metals portfolio will include the above four types of coins. Your Allegiance Gold coin expert will provide detailed insights into the advantages of each coin type, assisting you in selecting the most suitable options for your short and long-term investment goals.

Bullion Vs. Proof Vs. Numismatic Vs. Semi-Numismatic

Bullion coins closely track the spot price, historically showing no significant appreciation above it. However, they offer an excellent entry point into physical precious metals investments as they represent the underlying metal without any intrinsic value based on lower mintage.  

On the other hand, proof coins boast exceptional quality and limited annual production, commanding a higher value than bullion coins due to their unique characteristics and accompanying certificate of authenticity.

Numismatic coins are considered collectible and are not produced in modern times. Numismatic coins are generally worth more than their metal content because of the scarcity and grading nature of the coin.

Similarly, semi-numismatic coins have two upsides for price appreciation: movements in the spot price and limited availability when compared to bullion coins. Low-mintage coins are often sought after by collectors and investors alike because they further diversify portfolios and offer an additional feature of scarcity that may outperform their bullion counterparts.

When evaluating options for investing in types of Gold or Silver coins, it is important to consider your primary objectives. The ideal precious metals IRA portfolio will be diversified with various types of precious metals, i.e. Gold, Silver, Platinum, and Palladium further diversified by incorporating different types of IRS approved coins, such as bullion, proof, and semi-numismatic products..
