The Best Challenge Coins to Buy Right Now: Top Picks for Every Collector

This guide covers the five finest challenge coin designs available at One More Coin right now — ranked and reviewed for collectors, military enthusiasts, and anyone looking for a gift that means something.

What Makes a Challenge Coin Worth Buying

Not all challenge coins are equal. The difference between a coin worth owning and one that ends up in a drawer comes down to three things: design quality, historical or unit significance, and finish.

Design quality means high-relief sculpting, clear iconography, and detail that rewards close inspection. A challenge coin should look better the longer you look at it — not worse. 

Significance means the coin represents something real — a specific unit, a specific operation, a specific moment in military history. Generic "military" coins carry no weight. A coin that represents the SAS, Delta Force, or the 250th anniversary of the US Marine Corps carries the history of those institutions with it.

Finish means the coin feels like an object of quality — substantial weight, clean edges, a finish that holds its detail over time. Antique silver and gold-tone finishes both work well for military designs; the key is consistency and depth.

All five coins in this guide meet all three criteria. For a broader look at what makes challenge coins special, see our guide to military challenge coins: service, sacrifice and brotherhood.

1. US Marine Corps 250th Anniversary Coin

The US Marine Corps 250th Anniversary Coin is the standout commemorative piece in the collection. The USMC was founded on 10 November 1775 — 250 years of continuous service, the longest unbroken tradition of any branch of the US military. This coin marks that milestone.

The design features the Marine Corps Eagle, Globe and Anchor emblem in high-relief with anniversary detail — a coin that will only become more significant as the years pass. For any collector of American military history, or any Marine veteran or family member, this is the essential piece right now.

This piece is a US Marine Corps commemorative collectible coin designed for display and collection.

It's also the most time-sensitive coin in this guide — anniversary commemoratives have a natural relevance window. Own it now while the milestone is current.

2. SAS Special Air Service Challenge Coin

The SAS Special Air Service Challenge Coin represents one of the most elite and secretive military units in the world. Founded in 1941, the SAS set the template for special forces operations globally — their motto, "Who Dares Wins", is one of the most recognised phrases in military culture.

The coin features the SAS winged dagger emblem — instantly recognisable to anyone with knowledge of British military history — in a design that captures the unit's combination of precision and aggression. The antique finish gives it the weight and gravitas the subject demands.

This piece is a Special Air Service commemorative collectible coin designed for display and collection.

For UK collectors, military history enthusiasts, and anyone with a connection to British special forces, this is the most significant coin in the range.

3. Delta Force Challenge Coin

The Delta Force Challenge Coin represents 1st Special Forces Operational Detachment-Delta — the US Army's primary counter-terrorism unit and one of the most capable special operations forces in the world. Delta Force operates in the shadows; their coins carry that same quality of quiet authority.

The design captures the unit's identity without excess — clean, precise, and immediately recognisable to anyone familiar with US special operations. The coin pairs naturally with the SAS coin for a two-piece Anglo-American special forces set that covers the two most storied special operations traditions in the Western world.

This piece is a Delta Force commemorative collectible coin designed for display and collection.

4. US Army 1775 Challenge Coin

The US Army 1775 Challenge Coin commemorates the founding of the United States Army — 14 June 1775, over a year before the Declaration of Independence. The Army is the oldest branch of the US military and the foundation on which American military power was built.

The 1775 date gives this coin a historical weight that unit-specific coins don't always carry. It's not about a specific operation or a specific conflict — it's about the entire institution, from the Continental Army to the present day. For collectors of American military history, this is the foundational piece.

This piece is a US Army commemorative collectible coin designed for display and collection.

It pairs naturally with the Marine Corps 250th Anniversary coin for a two-coin American military heritage set that covers both the Army and the Marines.

5. Operation Midnight Hammer B2 Spirit Challenge Coin

The Operation Midnight Hammer B2 Spirit Challenge Coin is the most operationally specific coin in this guide — and the most visually striking. The B-2 Spirit stealth bomber is one of the most recognisable aircraft in military history: its flying wing silhouette is immediately distinctive, and its role in precision long-range strike operations has made it a symbol of American air power projection.

Operation Midnight Hammer refers to a specific B-2 strike mission — a coin that commemorates not just the aircraft but a specific moment of operational history. For aviation collectors, military history enthusiasts, and anyone drawn to the intersection of technology and conflict, this is the most distinctive coin in the range.

This piece is a B2 Spirit stealth bomber commemorative collectible coin designed for display and collection.

The design captures the B-2's silhouette in high-relief with operational detail — a coin that looks as impressive on a desk as it does in a display case.

How to Choose the Right Challenge Coin

With five strong options, the right starting point depends on what you're collecting for:

For American military history: Start with the US Army 1775 coin and the Marine Corps 250th Anniversary coin. Together they cover the two oldest branches of the US military and the full sweep of American military heritage.

For special forces: The SAS and Delta Force coins together make the definitive two-coin special forces set. Add the B2 Spirit for a three-coin set that covers ground, air, and covert operations.

For British military history: The SAS coin is the essential starting point. It's the most significant British military collectible in the range and the one with the broadest recognition.

For aviation: The B2 Spirit coin is the standout. There are few military aircraft with the same combination of visual distinctiveness and operational significance.

For gifting: The Marine Corps 250th Anniversary coin is the most immediately impressive — the anniversary context gives it a clear narrative that makes it easy to explain and easy to appreciate. For a veteran or active service member, match the coin to their branch or unit.

Displaying & Gifting Challenge Coins

Challenge coins display best when they're visible — not stored. A coin in a drawer is a coin that's been forgotten. A coin on a desk, a shelf, or in a shadow box is a daily reminder of what it represents.

Display options that work well for military challenge coins:

• Acrylic coin stand — upright display, face visible, works on any surface. The simplest and most effective option for a single coin.
• Velvet-lined tray — ideal for a set of three to six coins. Keeps them together and presentable.
• Shadow box frame — wall display for a themed set. Add unit insignia, photographs, or service ribbons alongside the coins for a full military display.
• Display case with lid — dust protection for longer-term display.

As gifts, challenge coins arrive securely packaged and are ready to present straight from the box. Free worldwide tracked shipping, delivered in 9–14 days. For veterans, active service members, military history enthusiasts, or anyone with a connection to the units represented, these are gifts that carry genuine meaning.
