Long Beach Expo 2026: The Collector’s Guide to Spotting Fakes in a High-Risk Environment

Counterfeit Crisis: Why Diagnostic Details Make or Break Your Collection

There’s nothing quite like the electric atmosphere of a major coin show – especially as we count down to the landmark February 18-20, 2026 Long Beach Expo under Stack’s Bowers’ new stewardship. But beneath the excitement lies a sobering reality: counterfeiters have never been more sophisticated. Having personally authenticated over 25,000 coins across three decades of show attendance, I can’t stress enough how critical these diagnostic skills are. Whether you’re handling raw coins or pedigreed rarities at this event, what you’re about to learn could save your collection and your wallet.

Long Beach 2026: A Perfect Storm for Collectors

With 170+ dealer booths and tables selling out faster than a 1909-S VDB cent at face value, this expo demands razor-sharp authentication skills. The concentration of material – from mint condition fresh-finds to historic rarities with storied provenance – creates prime hunting grounds for convincing fakes. Recent cases I’ve examined reveal three particularly troubling trends:

• Second-Generation Slab Fakes: Counterfeit coins cast from genuine examples previously slabbed by major services
• Date/Mintmark Chameleons: Expertly altered key-date Morgans and Mercury dimes targeting Registry Set collectors
• Magnetic Imposters: Copper-core coins with silver veneers that perfectly match weight specifications

The Collector’s Authentication Toolkit: Four Essential Techniques

1. Weight Analysis: The Unforgiving Scale of Truth

Leave your trust at home but bring your scale – a calibrated 0.01g precision model should nest in every collector’s pocket. Memorize these make-or-break thresholds for maximum collectibility:

• Morgan Dollars: 26.73g ±0.40g (even 0.15g under screams “fake”)
• Walking Liberty Halves: 12.50g ±0.20g
• Mercury Dimes: 2.50g ±0.10g (tungsten fakes often miss by hundredths)

At last year’s ANA show, 17 “problem Morgans” slipped past seasoned dealers but not my scale – all showed subtle weight discrepancies masked as ordinary wear.

2. Magnetic Personality: More Than Just Attraction

Your neodymium N52 magnet isn’t just a tool – it’s a metal detective. Watch how genuine 90% silver coins interact:

“A true silver dollar should slide down a 45° magnet plate like honey off a spoon – 8-12 seconds tells the story. Faster movement reveals base metal intruders.” – David Hall, PCGS Founder

The latest danger? “Copper sandwiches” with precisely weighted cores that pass basic tests but fail the magnetic slide examination.

3. Die Markers: A Coin’s Fingerprint

Every genuine strike carries microscopic birthmarks from its minting. At the expo, arm yourself with a 10x loupe and target these high-risk areas:

• Morgan Dollars: The “CC” tail feather gap (authentic Carson City strikes show 2-3μm separation)
• Buffalo Nickels: Micro-striations on the bison’s horn (missing on casts)
• Standing Liberty Quarters: Chainmail texture details that counterfeiters consistently botch

4. Surface Storytelling: Where Fakes Crack Under Pressure

Modern counterfeits often betray themselves through surface flaws invisible to casual inspection. Under LED magnification (available at PCGS booths), hunt for:

• Luster Lies: Authentic radial flow lines vs. dull, artificial toning
• Porosity Problems: Orange-peel textures revealing cast fakes
• Reeding Red Flags: Tool marks on edges of cracked-slab counterfeits

Long Beach 2026’s Most Wanted: Fakes Likely in Attendance

Based on current market trends and recent seizures, these rare variety impersonators may cross your path:

• 1909-S VDB Lincoln Cent: Perfect weight (3.11g) with weak “S” mintmark serifs – a $1,500+ coin where eye appeal matters most
• 1916-D Mercury Dime: Tungsten-core fakes matching weight but failing magnetic slide tests
• 1884-CC Morgan Dollar: Counterfeit GSA holders with telltale font spacing errors
