The Hunt for the 1800 ‘CROLUS’ Chilean Error: A Numismatist’s Journey

The Discovery That Changed Everything

Most collectors know that tiny details can transform a common coin into a numismatic treasure worth thousands. In 2014, at the COINEX fair in London, a dramatic error coin emerged that would captivate the numismatic world for years to come. Miguel Lehmann, founder of Numisor, shared footage with CoinWeek of an 1800-So AJ 8 Reales featuring one of the most spectacular minting errors ever discovered.

The coin bore “Carolus” misspelled as “CROLUS” – a mistake so glaring and dramatic that it immediately raised questions about authenticity. I had the privilege of seeing this coin personally at the show, having known Miguel from my time living in Europe and visiting his shop in Geneva. His excitement was palpable; he suggested the coin might be unique.

Initial Skepticism and Authentication Challenges

When the coin later appeared at auction in 2020 through Numisor, it realized approximately $15,000, purchased by @MrEureka. I acquired it from Andy recently after following its journey for over a decade. My initial reaction was skepticism – not uncommon when dealing with such dramatic errors.

Several factors gave me pause:

• The prevalence of sophisticated fakes from central and eastern Europe
• The lack of documentation for this error in published materials
• The irregular placement of letters that didn’t follow the uniform arc typical of well-executed dies

The odd placement of the letters, not following a uniform arc around the legends as noted by the CR in CROLUS and the H in Hispanic, gave me further pause.

However, Andy’s response was characteristically insightful: “What do you expect from such a dramatic error?” This perspective proved crucial in understanding how such mistakes occur.

Historical Context and Previous Appearances

My research uncovered the first documented appearance of this error in the 1991 Ponterio sale of the Viceroy Amat collection. A dark oxidized example marked the coin’s first public auction appearance. I later discovered another example, though I’m still tracking down the exact source of that information.

To further authenticate the piece, I reached out to contacts in South America to investigate local collections. One collector owned the Amat piece, while another revealed he had seen a specimen that served as the host for a Brazilian 960 Reis overstrike – potentially the key to proving authenticity.

The Breakthrough: Contemporary Evidence

Finding a 960 Reis overstrike using the CROLUS die would provide contemporary evidence of the coin’s legitimacy. After extensive searching, I obtained images from a South American collector just yesterday. While he claims he’ll “die with his collection” and has never sold a single piece, the images revealed crucial matching details.

The visible CR and H from HISPAN on the reverse (near STAB) confirmed the dies matched perfectly. Even more exciting, he mentioned knowing of a second CROLUS host coin in existence.

Understanding the Error: Die Analysis

The irregular letter placement that initially raised my suspicions actually provides insight into how this error occurred. When examining the coin closely, several key features become apparent:

Die Cracks and Stress Points

The uneven spacing suggests significant stress on the die during production. The misalignment of “CROLUS” indicates either:

• A poorly prepared master hub
• Significant wear on the working die
• A rushed production process at the Santiago mint

Double Die Characteristics

While not a classic doubled die, the error shows characteristics of multiple impression attempts. The letters appear slightly doubled in places, suggesting the die engraver may have attempted corrections or the hubbing process was imperfect.

Mint Mark Variations

The “So” mint mark (Santiago) appears correctly placed, confirming this was indeed a product of the Chilean mint rather than an alteration. The consistency of the mint mark across known examples strengthens the case for authenticity.

Comparative Analysis with Known Fakes

Several forum members raised valid concerns about the coin’s authenticity, drawing parallels to sophisticated fakes from Eastern Europe. However, several factors distinguish this piece:

• The undertype 960 Reis provides contemporary usage evidence
• The die match between multiple specimens confirms a genuine minting error
• The overall wear patterns and metal flow are consistent with 1800s silver coinage

This was highly sensible deduction by Mr. E! Dude LITERALLY screwed up the most “don’t eff THIS up” part of the coin – not exactly first ballot Diesinker Hall of Fame material!!

This observation perfectly captures the nature of the error – it’s so obvious that it could only be a genuine mistake, not a deliberate alteration.

Value and Collectibility

The 2020 auction result of approximately $15,000 provides a benchmark, but the discovery of additional specimens and the 960 Reis undertype may actually increase the coin’s value. Collectors of:

• Chilean numismatics
• Spanish colonial errors
• King Charles IV related coinage
• Dramatic mint error varieties

would all find this piece exceptionally desirable.

Authentication Checklist for Collectors

For collectors hoping to identify similar errors or authenticate this variety, consider these key markers:

Visual Inspection Points

• Letter spacing irregularities, particularly in “CROLUS”
• Misalignment of legends relative to the coin’s curvature
• Consistency of the “So” mint mark with other 1800s Chilean coinage
• Metal flow patterns consistent with 18th-century minting techniques

Die Match Verification

• Compare the position of the CR in CROLUS
• Examine the H in HISPAN on the reverse
• Check for matching die cracks or stress points
• Verify the placement of STAB in the reverse legend

Historical Significance

This error provides fascinating insight into colonial minting practices. The dramatic nature of the mistake – misspelling the king’s name on official currency – suggests either:

1. Significant pressure on mint workers to produce coins rapidly
2. Limited oversight or quality control at the Santiago mint
3. Possible political tensions affecting production quality

The fact that multiple examples exist indicates this wasn’t a one-off error but rather a die that entered production with the mistake intact.

Conclusion: A Numismatic Treasure

The 1800 “CROLUS” Chilean 8 Reales represents one of the most dramatic and well-documented mint errors in Spanish colonial numismatics. From its initial discovery at COINEX 2014 to the recent authentication through the 960 Reis undertype, this coin’s journey exemplifies the detective work that makes numismatics so compelling.

For collectors, this piece demonstrates that sometimes the most valuable coins are those with the most obvious mistakes. The irregular letter placement that initially raised suspicions ultimately provided the key to understanding how such a dramatic error could occur and survive in multiple specimens.

As one forum member aptly noted, finding the 960 Reis undertype was “quite a needle in a haystack” – but that’s precisely what makes this discovery so significant. It transforms what could have been dismissed as a modern fabrication into a documented historical artifact with multiple surviving examples.

The hunt continues for the second known CROLUS host mentioned by the South American collector, and perhaps one day the owner of the 960 Reis undertype will decide to part with his treasure. Until then, the 1800 “CROLUS” error remains a testament to the enduring appeal of mint errors and the meticulous research required to authenticate them.
