How to Spot Rare Errors at the Revived Long Beach Coin Show

Most collectors know the thrill of finding something special—but too often, we walk right past it. Whether you’re weaving through the crowded aisles of the revitalized Long Beach Coin & Collectibles Expo or sifting through a fresh batch of raw coins at home, understanding the small signs that boost a piece’s numismatic value can lead to real discoveries. From die cracks to off-center strikes, these subtle quirks are often overlooked—but they can mean big rewards for those who know what to look for.

Last week’s Long Beach show—now under new management with Stack’s Bowers at the helm—was buzzing with energy and opportunity. Amid stacks of Walking Liberty Half Dollars, Lincoln Cents, and Morgan Silver Dollars, countless rare varieties sat quietly waiting for someone with a trained eye to spot them. If you missed one, don’t worry; there’s always next time. But first, let’s explore what separates an ordinary coin from one with hidden treasure tucked away in plain sight.

The Revitalized Long Beach Show

The historic Long Beach Expo has returned with renewed vigor since being taken over by Stack’s Bowers. Though some longtime vendors like Legend weren’t spotted this go-around, the event still stands tall as one of the West Coast’s best gathering places for enthusiasts. Dealers shared stories of strong demand—not just for pre-1965 silver coins, but also vintage U.S. paper currency, prized for their distinct serial numbers and seal colors.

Amid hundreds of bins and thousands of coins, dozens of rare anomalies were likely sitting unnoticed—waiting patiently for someone with curiosity and magnification to reveal their secrets.

Among the finds mentioned by several attendees was an uptick in Mexican coins and wartime bronze issues—like 1943 steel pennies and 1944 zinc-coated cents. These aren’t just nostalgic relics; in the right condition, even slight imperfections in strike or alignment can dramatically affect a coin’s desirability and collectibility.

Die Cracks: Hidden Treasures on Display

A die crack forms when the metal dies used to stamp coins develop fractures from constant pressure and heat—an inevitable part of mass production. On a finished coin, this fault manifests as raised lines that mirror the original crack. Depending on size and placement, these flaws can be worth mere cents—or hundreds of dollars.

Look Out For:

• Elevated ridges appearing across open fields or devices
• Jagged lines branching near letters or key design points
• Secondary doubling caused by stress shifting the die mid-strike

Many newcomers skip over these details, assuming they’re insignificant. But experienced collectors understand that prominent examples—such as a full-collar crack cutting across Lady Liberty’s face on a Walking Liberty half dollar—can send a coin’s eye appeal soaring straight into auction catalogs. In mint condition, these specimens hold even greater allure.

Double Dies – Where Repetition Goes Awry

This type of error isn’t simply a mechanical slip—it’s nature conspiring against order. During the die-making process, if the hub impresses twice but shifts ever so slightly in between, the result is a double die, complete with ghost-like duplications that stand proud from the surface. Unlike flat, post-strike doubling, a true doubled die carries physical relief—a telltale clue to savvy collectors.

Telltale Signs Include:

• Noticeable duplication in numerals, especially dates
• Strong clarity in lettering, particularly below mottoes or legends
• Subtle shadows along facial features or national symbols

We all know about the iconic 1955 Doubled Die cent—but did you realize similar patterns exist on much earlier dates? Take, for example, certain 1918 Standing Liberty quarters, where doubling subtly affects the date block. Next time you sort through MS 65 slabs, give those inscriptions a closer glance—you might find yourself staring down a long-forgotten rare variety.

Mint Marks – More Than Just Letters

Small yet mighty, mint marks play a critical role in identifying origin and authenticity. But things get interesting when mistakes happen. Misplaced, absent, or duplicated mint marks may seem trivial—but in the numismatic world, they’re anything but. The infamous case of the 1943-S nickel missing its “S” mark is just one illustration of how die mix-ups can create highly sought-after gems.

Keep an Eye On:

• Missing mint marks in expected locations
• Mark positions that deviate from standard norms
• Faint or blurred impressions due to die wear

Bulk lots of Walking Liberty halves or Trade dollars are goldmines for these kinds of irregularities. Don’t shy away from asking dealers about expected specifications—the right question could save hours of searching, or worse—missed opportunities entirely.

Off-Center Strikes & Coining Chaos

When a blank disc misses its center alignment before striking, chaos ensues—sometimes quite literally. These off-center errors vary wildly in impact. Mild cases might escape notice without magnification, but extreme displacements—with barely any imagery transferred—transform everyday coins into stunning conversation starters within error communities.

Other Mechanical Wonders:

• Broadstrikes—in which collars malfunction, expanding the flan unnaturally wide
• Cuds—caused by clogged portions of the die obscuring design elements
• Lamination faults—thin layers separating internally post-mint

Older series—especially Indian Head Cents, Draped Bust dimes, or Seated Liberty silver—are hotspots for mechanical missteps. As one attendee noted: keep digging through those bargain bins marked “$10-$25 Large Cents.” With patience, light, and a loupe, you might stumble upon something truly unexpected hiding in the most unlikely spots.

Grading Errors – Not All Mistakes Are Created Equal

Just because you’ve found a flaw doesn’t mean it’s rare—or valuable. Authenticity comes first, followed by grading standards set by reputable services like PCGS, NGC, and ANACS—all of whom were actively present at last week’s expo. A professional slab can validate everything from luster to legitimacy and amplify market appeal considerably.

What Elevates a Piece:

• Prominent visual distinction compared to regular releases
• Series popularity among advanced collectors
• Coin’s overall preservation and mint condition
• Population data confirming low survival rates

A broadstrike in a common-year Walking Liberty half might sell for $100–$300 in AU to Mint State grades, depending on aesthetics. However, identical damage on a scarcer date—say, a 1919-D—could bring four figures at auction. Context matters—one mistake does not define value alone. Numismatics rewards precision paired with knowledge.

Final Thoughts – Become a Detective, Not Just a Buyer

Error collecting isn’t about hoarding oddities blindly—it requires skill, care, and curiosity. By learning how to distinguish die cracks from grease-filled gaps, or spotting subtle doubled letters beneath legend text, you become more than just another hobbyist—you evolve into a sharp observer capable of transforming random finds into cherished keepsakes.

So next time you’re browsing Pierre Fricke’s legendary jar of Large Cents or exploring NGC submission queues trying to authenticate a curious specimen, remember this truth: every coin holds possibility until proven otherwise. Because somewhere between eager sellers and cautious buyers lies the next great discovery—just waiting for someone bold enough to look a little closer.
