Decoding Authenticity: Expert Guide to Spotting Fake George I & II Crown Coins

With Counterfeits Flooding the Market, These Diagnostic Points Could Save Your Collection

After three decades of hands-on authentication work, a troubling trend keeps me awake at night: the flood of sophisticated fakes targeting 18th-century British crowns. The rare George I 1720/18 and George II 1741 issues – the crown jewels of any serious collection – now fetch five-figure sums in mint condition, making them prime targets for forgers. Today, I’ll share the insider knowledge I’ve gained examining hundreds of these coins, revealing key diagnostics that separate genuine treasures from convincing counterfeits.

Historical Significance: Why These Crowns Command Such Devotion

The George I (1714-1727) and George II (1727-1760) crown series represent the ultimate challenge for British numismatists. Their combination of historical weight and extreme scarcity creates perfect storm of collectibility. As our forum discussion revealed, surviving populations are astonishingly low – only four specimens of the legendary 1720/18 George I crown have crossed the grading table at PCGS across all grades. The Standard Catalogue classifies this overdate as R2 (rare) in Extremely Fine condition, with other dates ranging from scarce to “once-in-a-collecting-lifetime” R4 status.

“This series separates casual collectors from true specialists. The modest mintages and often weak strikes make high-grade survivors exceptionally rare” – Forum Collector

The George II 1741 young head crown presents different challenges. Its breathtaking high-relief strike makes authentication particularly nuanced, as one sharp-eyed collector observed:

“You need to differentiate between natural weakness in the portrait’s hair details and actual wear. The fields tell the real story” – Forum Contributor

The Nuts and Bolts of Authentication: Key Diagnostic Markers

Weight and Dimensions: Your First Reality Check

Genuine specimens should feel substantial in hand – between 28.1g and 29.5g (about one troy ounce) with a diameter spanning 38-40mm. I’ve seen modern fakes stumble at this first hurdle, like a supposed 1720/18 that came in 0.7g underweight due to inferior metals. Invest in a jeweler’s scale precise to 0.01g – in this rarefied collecting tier, even a slight deviation can signal trouble.

The Metal Doesn’t Lie: Composition Tests

These crowns left the mint as .925 sterling silver masterpieces. Use these essential verification methods:

• Magnet Test: Authentic pieces will show zero attraction – many contemporary fakes use magnetic cores beneath silver plating
• Specific Gravity: Should register between 10.2-10.4 when tested properly
• Edge Examination: Look for seamless milling with consistent depth – casting seams scream “fake”

Telling Details: Die Markers That Never Lie

Under 10x magnification, the legendary 1720/18 overdate reveals its secrets:

• The ghostly “8” lingering beneath the final “0” in the date
• Softness in George I’s eyebrow and crown jewels characteristic of original dies
• Signature die cracks between Britannia’s shield and right leg

For the magnificent 1741 George II crowns:

• High points in the hair above the ear often show incomplete striking
• Uniform “grains” in denticles – irregular pellets indicate modern tooling
• Genuine reverses display subtle doubling in lettering

As our forum case study beautifully demonstrated:

“The original cartwheel luster dances across the fields when tilted – especially on the reverse” – Original Poster

This living, breathing surface quality separates true mint-state pieces from dead, artificial finishes.

Fakes We’re Fighting: Current Counterfeit Trends

In my years handling these crowns, five counterfeit types repeatedly surface:

• Chinese Electrotypes: Correct weight but porous surfaces lacking original luster
• Indian Subcontinent Castings: Underweight specimens with mushy details
• “Museum Replicas”: Modern dies create artificial sharpness missing period character
• Altered Dates: Common 1723 coins doctored to mimic the rare 1720/18 – check for tool marks in the date area

One collector’s wisdom perfectly captures the mindset needed:

“Collect the coin, not the date. If it’s too good to be true, walk away. There will always be another opportunity” – Forum Member

Advanced Authentication: Bringing In the Big Guns

When a potential crown jewel surfaces, employ these professional techniques:

1. Surface Study: USB microscopes reveal casting pits and modern tooling
2. Ultrasonic Testing: Uncovers hidden repairs or filler metals
3. XRF Spectrometry: Non-destructive silver purity confirmation
4. Comparative Analysis: Stack your candidate against PCGS-certified examples like our forum contributor’s prize:

“This beauty represents the pinnacle of my collection – one of just four graded by PCGS across all categories” – Original Poster

While third-party certification provides peace of mind, stay vigilant – I’ve seen convincing fake slabs containing electrotype copies.

Numismatic Value: Why Authentication Matters

Proper vetting makes staggering value differences:

As our forum contributor noted when discussing condition rarity:

“When a rare variety surfaces, understanding its true place in the numismatic hierarchy prevents costly mistakes” – Original Poster

Conclusion: Protecting Your Piece of History

The George I 1720/18 and George II 1741 crowns represent numismatic perfection – artifacts that bridge our era with Britain’s Age of Enlightenment. Their combination of historical gravitas and extreme scarcity demands respect and rigorous authentication. By mastering these diagnostics – from weight tolerances to die characteristics and surface patina – you join an elite circle of custodians preserving these masterpieces.
