Finding 1800 CROLUS Chilean Error in the Wild: A Cherry Picker’s Guide

Introduction: The Thrill of the Hunt

You don’t always need a dealer to find this. Here is what to look for when searching through circulation or bulk lots. The 1800 CROLUS Chilean error represents one of those extraordinary finds that can still surface in unexpected places, waiting for a sharp-eyed collector to recognize its significance.

Historical Significance of the CROLUS Error

The 1800 CROLUS error coin tells a fascinating story of human error in the minting process. This dramatic mistake occurred when the die engraver misspelled “Carolus” – the Latin form of King Charles – as “CROLUS” on an 8 Reales coin from the Santiago mint in Chile. The error appears on the obverse legend, creating one of the most dramatic spelling mistakes in colonial Spanish coinage.

The coin first surfaced publicly in the 1991 Ponterio sale of the Viceroy Amat collection, where a dark oxidized example marked its initial appearance in a public auction. For decades, numismatists debated its authenticity, with some questioning whether such a dramatic error could be genuine.

Identifying Key Markers

When searching through bulk lots or estate collections, look for these critical markers:

• Date and Denomination: 1800, 8 Reales
• Mint Mark: “So” for Santiago
• The Error: “CROLUS” instead of “CAROLUS” in the obverse legend
• Die Characteristics: Notice the odd placement of letters – the CR in CROLUS and the H in HISPAN don’t follow the uniform arc typical of properly engraved dies

The irregular letter placement actually supports authenticity. As one collector noted when discussing their initial skepticism: “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.” This irregularity is precisely what you’d expect from such a dramatic error – the engraver clearly wasn’t at their best that day!

Authentication Through Undertype Evidence

One of the most compelling pieces of evidence for the CROLUS error’s authenticity came through an unexpected discovery. A Brazilian 960 Reis coin was found that had been struck over a CROLUS host coin. This undertype evidence provided contemporary proof of the error’s existence.

The undertype showed visible portions of the CR from CROLUS and the H from HISPAN on the reverse, matching the dies of known examples. As one researcher explained: “The first evidence I can find of the coin is in the 1991 Ponterio sale… I did find one other example, though I have to go back through my research to figure out where I found it.”

“After acquiring the coin, I reached out to some of my contacts in South America to see if there were other examples that were notable in local collections. One individual owns the Amat piece while another suggested to me that he had seen one which was the host coin for a Brazilian 960 R.”

Where to Search: Circulation Finds and Bulk Lots

The CROLUS error can still be found by diligent collectors searching through:

Estate Sales and Collections

Older collections, particularly those assembled before the error became widely known, may contain overlooked examples. The coin’s dramatic appearance can sometimes cause casual observers to dismiss it as damaged rather than recognizing it as a genuine error.

Bulk Lots and Mixed Accumulations

Large accumulations of Latin American or Spanish colonial coins are prime hunting grounds. The CROLUS error might be mixed with other 8 Reales pieces, requiring careful examination of each coin’s legends.

Circulation Finds

While less common today, coins from the 1800s occasionally still surface in old collections or from families with generational ties to Latin America. The key is knowing exactly what to look for.

Understanding the Value

The 1800 CROLUS error has demonstrated significant value in the collector market. When Numisor offered the coin for sale in 2020, it realized approximately $15,000. This price reflects both its rarity and the authentication provided by the undertype evidence.

Several factors contribute to its value:

• Rarity: Potentially unique or nearly so
• Historical Significance: A dramatic mint error from the colonial era
• Authentication: Confirmed through undertype evidence
• Eye Appeal: The dramatic nature of the error makes it visually striking

Research and Documentation

Thorough research is essential when evaluating potential CROLUS errors. The coin’s history includes:

• Initial appearance in the 1991 Ponterio sale
• Public exhibition at the 2014 COINEX fair in London
• Documentation in CoinWeek video coverage
• Authentication through Brazilian 960 Reis undertype evidence

“Initially, I was skeptical that the coin was real. My concerns stemmed from the fakes which have come out of central and eastern Europe, and the lack of documentation of this error in previous published materials,” noted one researcher who later acquired the coin. This skepticism is healthy and appropriate when evaluating rare errors.

Red Flags and Authentication Tips

When examining potential CROLUS errors, be aware of these considerations:

• Die Match Verification: Compare the letter spacing and die characteristics with documented examples
• Metal Composition: Should match standard 8 Reales specifications
• Wear Patterns: Should be consistent with circulation if claimed as such
• Provenance Research: Trace the coin’s history when possible

The uneven legend lettering, initially concerning to some researchers, actually supports authenticity. “What do you expect from such a dramatic error?” was the appropriate response from an experienced collector when this concern was raised.

Similar Authentication Cases

The CROLUS error isn’t the only case where undertype evidence has proven a coin’s authenticity. As one collector noted: “Not the first time a 960R has proven a type to be contemporary and/or genuine. There’s that one British Honduras GR stamp that was thought to be a fabrication but then it surfaced as a Brazil overstrike host.”

Conclusion: The Collector’s Reward

Finding a 1800 CROLUS error represents the ultimate cherry-picking success story. It combines historical significance, dramatic visual appeal, and the thrill of discovering something truly rare in unexpected places. Whether searching through estate sales, bulk lots, or inherited collections, the key is knowing exactly what to look for and maintaining the patience to examine each coin carefully.

The CROLUS error reminds us that extraordinary finds still exist for those willing to do the research and maintain a sharp eye. As the discovery of the Brazilian undertype proved, sometimes the most compelling evidence for a coin’s authenticity comes from the most unexpected sources. Happy hunting!
