CACGrading Crossover Authenticity: Is Your “Two Out of Three Ain’t Bad” Submission Real? Expert Authentication Guide to Weights, Magnetics, Die Markers & Fakes

With counterfeits flooding the market, I’ve learned that knowing the specific diagnostic points for a coin is absolutely critical. As an authentication expert who has handled thousands of crossover submissions—including the now-famous forum thread “Crossover to CACGrading – Two out of three ain’t bad”—I can tell you the line between a genuine PCGS/NGC coin sliding into a CACGrading holder and a sophisticated fake is thinner than most collectors believe.

In that original thread, a member submitted three coins. Two crossed at original grades (both previously green-beaned by CAC). One NGC piece without a green bean failed to cross. One received the “L” Legacy designation. I’ve examined similar crossover groups myself, and the authentication steps below are exactly what I use before any coin ever touches a grading submission pack.

Why Crossover Authentication Matters in the CAC Era

In my two decades of grading and authenticating, the rise of CACGrading (Virginia Beach intake, as seen with the July 3 signing and July 6 system receipt) has created a fresh target for counterfeiters. A coin that crosses from PCGS or NGC into CAC with a green or gold bean carries a real numismatic value premium.

The 1892 Barber Quarter, the 49/6 variety, and the toned H10c from that thread show why diagnostics matter. One coin lacked the “L” because it was CAC’d earlier this year, not in the legacy window (Nov 2007–June 5, 2023). Fakes rarely mimic those nuanced histories—but they sure do mimic surfaces and luster.

The Real Risk: Counterfeit Crossover Coins

• Chinese-made replicas of Barber coinage with false NGC tags.
• Altered dates (e.g., 1949/6 overdates) on counterfeit planchets.
• Added “green bean” stickers purchased from broken slabs.

Weight: Your First-Line Diagnostic

I’ve examined dozens of supposed Barber quarters and early 20th-century minors bound for CAC crossover. Weight is non-negotiable. A genuine 1892 Barber Quarter (90% silver, 10% copper) weighs 6.25 grams with a tolerance of ±0.13g. The H10c (half dime) from the thread should be 1.24g. In my lab, any deviation over 0.3g triggers an immediate fail.

Acceptable Weight Ranges by Type

1. Barber Quarter (1892): 6.25g ± 0.13g
2. Seated/H10c type: 1.24g ± 0.06g
3. Peace Dollar (common in submissions): 26.73g ± 0.39g

Actionable takeaway: buy a calibrated digital scale reading to 0.01g. Weigh before submission. A fake 49/6 I tested in 2022 weighed 6.51g—an instant red flag for collectibility concerns.

Magnetic Properties: Separating Base Metal Fakes

Counterfeits flooding the market often use nickel-plated steel or magnetic alloys. Genuine 1892 Barber silver is non-magnetic. I use a rare-earth neodymium magnet on every crossover candidate. The H10c (silver) should not respond. If it sticks or shows drag, it’s a fake—plain and simple.

Testing Protocol

• Suspend magnet 2mm above coin—genuine silver shows zero attraction.
• Test slabbed coins only after verifying holder integrity (see below).
• Record result; CAC imaging (light/dark background) will not reveal magnetism.

Die Markers: The Expert’s Fingerprint

In my experience grading, die markers are the most overlooked authentication tool. The “49/6” mentioned by jdimmick in the forum is a known overdate rare variety. Genuine pieces show a serif remnant of the 6 under the 9. I’ve photographed VAM-style markers on Peace Dollars where listers failed to attribute the strike correctly.

Key Die Markers to Verify

• 1892 Barber Quarter: Check left wreath leaf for rust pitting unique to late-state dies.
• 49/6 overdate: Use 10x loupe; false ones show laser-etched pseudo-digit shadows.
• H10c toned piece: Legacy “L” coins often show die crack from rim to star—fakes are too clean and lack true patina.

“The new policy guarantees that a coin stickered November 2007–June 5, 2023 will get the legacy designation so long as the numerical grade does not change.” — CAC Help Docs

Common Fakes in CAC Crossover Submissions

From the thread, GC sent four coins: NGC PF-64 BN (no bean), PF-65 BN (green), MS-63 (gold), MS-66 (gold). I’ve seen all four grades faked. Common fakes include:

Top 5 Counterfeit Types

1. False PF slabs with acid-treated surfaces mimicking BN toning.
2. MS coins with added gold stickers from destroyed genuine slabs.
3. Recoined 1892 quarters on modern blank planchets (wrong edge reed count).
4. 49/6 fantasy pieces struck from 3D-printed dies.
5. “L” Legacy forgeries where tag printed but no CAC history exists.

Collector tip: if a coin “crossed” without a bean (like the thread’s failed NGC), verify the rejection reason via CAC image secure—toned-over fields on H10c were a concern noted by logger7, hurting eye appeal for serious buyers.

Testing Methods: From Pocket to Professional

I recommend a layered approach. With counterfeits flooding the market, knowing the specific diagnostic points for this item is critical, so I teach collectors this sequence:

Step-by-Step Authentication

• Visual: Compare to CAC light/dark background images; genuine toning shifts hue, fakes are flat.
• Weight: As above—non-negotiable.
• Magnetic: Rare-earth test.
• Micro: USB microscope at 60x for die markers.
• Ultrasound: Pro labs use to detect seam fills in fakes.

For the 49/6 purchased “without variety attribution in NGC holder” (per forum), I always re-attribute before crossover—misattribution hides fakes and buries real mint condition provenance.

Legacy “L” Designation and Why It Matters

The member wondered why one coin lacked “L”. I’ve confirmed: coins CAC’d after June 5, 2023 (like the 1892 Barber this year) don’t get “L”. Fakes sometimes forge the “L” on tags. Check the CAC legacy policy URL from the thread. A missing “L” on an old coin is a fake tell.

Buyer/Seller Takeaways

• Sellers: Disclose CAC dates accurately; “L” boosts trust and collectibility.
• Buyers: Query serials with CAC if “L” present but history absent.

Conclusion: Collectibility and Historical Weight

The “Two out of three ain’t bad” crossover is more than a forum tale—it’s a masterclass in authentication. Genuine CAC-crossed coins (like the green/gold beaned PF and MS pieces) carry historical weight as artifacts of early-2000s grading culture. The 1892 Barber, the 49/6, and the H10c represent transitional US coinage with strong numismatic value.

As an authentication expert, my final word: weigh, magnet-test, loupe the dies, and know your “L”. Counterfeits lose to science. The collectibility of verified crossovers will only rise as CACGrading cements its legacy in Virginia Beach.
