A peculiar conical copper object discovered in Southeast Iowa has sparked a flurry of speculation and intrigue among internet users. Found by a metal-detecting enthusiast, the mysterious item has ignited countless theories as to its origin and purpose. Could it be a relic of a bygone era, a component of a long-forgotten device, or perhaps something far more significant? Let’s take a closer look at what we know about this fascinating find.

The Discovery: A Metal Detector’s Treasure
The strange object was uncovered by a Reddit user while metal detecting on a homesite in Southeast Iowa. The site, which dates back to approximately 1900-2011, yielded the intriguing artifact buried about five inches below the surface. Its metallic nature initially caught the detector’s attention, with the object emitting a sound similar to that of a copper penny.
Upon closer inspection, the user described the object as being made of copper, although it was unclear whether it was plated with nickel, chrome, or silver. They provided detailed measurements: the cone is about 1¾ inches from tip to base, with a 2½-inch wide base. The piece also features two holes drilled near the top, positioned roughly at 10 and 2 o’clock when laid flat. Interestingly, the top portion of the cone can spin in both directions while the base remains stationary. The item’s weight was estimated to be approximately 45.36 grams—roughly the equivalent of eight quarters.
Theories About the Object’s Purpose
As the post gained traction online, users from various communities offered their insights and theories. The unique design of the object, combined with its unusual spinning feature and drilled holes, led to a wide array of possible explanations.
- Oil Lamp Component: Some users speculated that the object might be part of an oil lamp, with the conical shape serving as a middle piece where fuel exits. This theory aligns with the design’s practical yet decorative appearance.
- Finial: Another popular suggestion was that the object could be a finial—a decorative top for a lamp or similar household item. The presence of drilled holes and a spinning top piece suggested it might have been attached to another structure.
- Incense Burner Lid: The conical shape and drilled holes also led some to believe it might be the lid of an incense burner, designed to allow smoke to escape gracefully.
- Drawer Knob: Others proposed it might be a drawer knob, with the holes allowing it to be fastened securely to furniture.
- Military Connection: A less conventional but intriguing suggestion was that the object might be related to the iconic German military helmet, the Pickelhaube. This theory arose from the object’s resemblance to the spiked adornments often seen on these helmets.

Could It Be a Pickelhaube?
The suggestion that the object might be connected to the Pickelhaube—a historic German military helmet—added a new layer of intrigue. The Pickelhaube, with its distinctive spike, was introduced in the 1840s by King Friedrich Wilhelm IV of Prussia. Initially crafted from leather, the helmet often featured brass or metal fittings, including spikes and insignias representing rank and unit.
While the object’s spinning feature and lack of structural reinforcement cast some doubt on this theory, its shape and material make it plausible as a decorative or functional piece from a military artifact. The Pickelhaube remains a significant symbol of German militarism and efficiency, and if the object is indeed related, it could hold historical value.

Design Details: What the Object Tells Us
The object’s unique characteristics offer several clues about its purpose:
- Copper Material: The copper construction suggests durability and potential decorative intent. Copper was often used in household items, tools, and decorative pieces in the early 20th century.
- Spinning Top: The spinning feature adds an element of complexity, indicating it may have been part of a mechanical or functional device rather than purely decorative.
- Drilled Holes: The drilled holes imply it was attached to another object or structure, possibly with screws or nails. Their placement suggests functionality over ornamentation.
- Conical Shape: The shape hints at its potential use in directing or dispersing something—be it light, smoke, or even liquid.

Speculation Versus Certainty
While many of the theories proposed by internet users are plausible, none can be confirmed without further investigation. The object’s exact purpose remains a mystery, but its discovery highlights the value of collective curiosity and shared expertise. It’s a reminder that even the most ordinary-seeming items can hold fascinating stories.
What Is the Pickelhaube?
For those unfamiliar, the Pickelhaube was a spiked helmet worn by German soldiers in the 19th and early 20th centuries. Its design, though iconic, offered minimal practical protection in combat. Made from leather with metal fittings, the helmet was more ceremonial than functional, symbolizing rank and status within the military.

By the early 20th century, the Pickelhaube was largely replaced by the Stahlhelm, a more practical steel helmet better suited for modern warfare. However, the Pickelhaube remains a sought-after collector’s item and an enduring symbol of German military history.
If the copper object is indeed linked to a Pickelhaube, it could represent part of the decorative fittings or adornments that were often crafted from durable metals like brass or copper.

The Power of Online Collaboration
This story isn’t just about a mysterious object—it’s also a testament to the power of online communities. Platforms like Reddit bring together enthusiasts from all walks of life, enabling collaborative problem-solving and shared learning. From history buffs to engineering experts, everyone has a chance to contribute their knowledge and perspectives.
The conical copper object is a perfect example of how the internet can turn a small discovery into a global conversation. While we may not have definitive answers yet, the theories and insights offered by users highlight the joy of curiosity and exploration.

Conclusion: The Mystery Lives On
The conical copper object found in Southeast Iowa continues to baffle and intrigue, sparking discussions across online communities. Whether it’s a piece of an oil lamp, a decorative finial, or even a connection to the historic Pickelhaube, its true purpose remains a mystery for now. What’s certain, though, is that discoveries like these remind us of the stories hidden beneath the surface, waiting to be uncovered.
This enigmatic artifact is more than just a relic—it’s a symbol of the enduring human desire to learn, share, and connect.
