Eleven rare silver coins, buried during the first century BC, have emerged from beneath a former sports field in Germany. The discovery is more than a story about hidden treasure: it offers a rare glimpse into the movement of wealth, trade and people across Celtic Europe more than 2,000 years ago.
Imagine spending your childhood playing football on a field, never suspecting that beneath the ground lies a small fortune from an ancient civilisation. Generations come and go, the landscape changes, and the original owner disappears into history. Then, during preparations for a construction project, archaeologists uncover something that has remained buried for more than two millennia.
That is the remarkable story behind a recent discovery in Singen, in Germany’s central state of Thuringia.
Archaeologists investigating a former sports field ahead of construction of a new fire station recovered a group of 11 ancient Celtic silver coins. Dating to the first century BC, the coins form the largest known hoard of their period recorded in Thuringia.
The coins themselves cannot tell us everything. But their design, location and archaeological context provide clues to a world that existed long before modern Germany took shape.
An ordinary construction site with an extraordinary secret
The initial coins were discovered during archaeological work in July and August 2025. Follow-up excavations in August 2026 helped researchers establish that the scattered objects belonged to a single deposit rather than representing unrelated losses over many centuries.
That distinction is crucial.
Archaeologists call a group of objects deposited together at one time a closed find. When researchers can establish that coins were buried as a single group, they can investigate the circumstances of their deposition and compare them with other discoveries from the same period.
At Singen, the 11 coins were spread across an area measuring approximately 5.8 metres by 1.5 metres. Researchers believe centuries of ploughing probably displaced them from their original positions.
The container in which they were buried has not survived. Archaeologists suspect it may have been made from organic material that gradually decomposed. No surviving container has been identified, so the precise method of concealment remains uncertain.
The field’s modern appearance concealed a complicated archaeological history. The discovery also illustrates why investigating a site before construction can be so important: without proper examination, buried objects might be disturbed or destroyed without their historical context being recorded.
What were the ancient Celtic coins worth?
The coins are known as Prague-type quinarii, a form of silver currency associated with Celtic communities in central Europe during the final centuries BC.
Their classification is based on their characteristics and comparison with other known examples. Numismatists—the specialists who study coins—use details such as shape, weight, imagery and manufacturing techniques to investigate where and when coins were produced.
The Thuringian State Office for Heritage Management and Archaeology reported that only around 80 examples of this coin type had previously been identified across the region. The Singen discovery therefore represents a substantial addition to the known archaeological record.
Their modern archaeological importance is clear. Their purchasing power in the first century BC, however, cannot be established from the number of coins alone. Their value would have depended on the economic circumstances of the time, the amount of silver they contained and the goods or services for which they could be exchanged.
There is also no evidence that the owner intended to create a spectacular treasure hoard. Eleven coins could have represented personal savings, money set aside for a transaction or a small reserve of valuable metal.
What makes the discovery exceptional is not necessarily the size of the fortune. It is the rarity of this particular coin type in Thuringia and the fact that the coins appear to have been deposited together.
Who buried the coins—and why never return?
This is the mystery at the heart of the discovery.
Someone possessed these silver coins around 2,000 years ago and placed them somewhere they could not easily be found. Yet the owner, or anyone who knew about the hiding place, apparently never recovered them.
Several explanations are possible, but none has been established.
A precaution during uncertain times: The owner may have concealed the coins for safekeeping during a period of insecurity. Burying valuable possessions was one way people could protect wealth when carrying it openly was risky.
Savings awaiting collection: The coins may have been hidden temporarily while their owner travelled, conducted business or arranged a future transaction. If the person died, moved away or became unable to return, the hiding place might have been forgotten.
A deposit with another purpose: It is also possible that the coins were placed together for a reason that cannot now be reconstructed. Archaeologists have not established whether the deposit was connected to a specific event, ritual or emergency.
These remain hypotheses, not confirmed explanations.
The most compelling part of the story is the gap between the moment of concealment and the modern discovery. We can identify the coins and estimate when they were buried, but the personal circumstances behind their disappearance remain unknown.
That uncertainty is not a weakness in the discovery. It is a reminder that archaeological evidence often preserves objects more successfully than it preserves the intentions of the people who used them.
Could the coins reveal an ancient Celtic trade network?
Researchers believe the mint responsible for producing Prague-type quinarii found in Thuringia may have been located in the Gotha region, northwest of Singen. The discovery therefore provides another piece of evidence for investigating how coins and goods moved through this part of central Europe.
Thuringia contains numerous archaeological sites associated with Celtic communities. One important site is the Steinsburg near Römhild, which is associated with Celtic settlement and craft production.
Mapping coin discoveries alongside settlements, production centres and other archaeological evidence can help researchers investigate connections between these places.
The Singen hoard does not prove that its owner travelled from Gotha or that the coins followed a particular trade route. However, it gives researchers a valuable geographical data point that can be compared with other finds.
Coins can travel considerable distances through trade, payments, gifts and exchanges between communities. Studying where particular types appear may help archaeologists reconstruct the economic relationships that existed before written records became widespread in a region.
In this case, just 11 coins may help refine our understanding of Celtic monetary activity in Thuringia.
The other objects found beneath the field
The silver hoard was not the only discovery made during the archaeological investigations.
Researchers also recovered objects from different periods, including a Roman denarius dated to AD 164–169, a medieval glass bead, a knife fragment, another silver coin and a Prussian uniform button from the nineteenth or twentieth century.
These finds do not all belong to the same historical episode. In particular, the Roman coin is considerably later than the Celtic hoard.
Their presence illustrates how a single location can accumulate evidence from many different periods. Fields are cultivated, buildings are constructed, objects are lost and soil is repeatedly disturbed. Over centuries, these activities can bring together artefacts that originally had nothing to do with one another.
That is why archaeological context matters. A coin discovered alongside another object is not necessarily connected to it. Researchers must establish dates, locations and relationships before drawing conclusions.
The Singen discovery also demonstrates why undocumented collecting can destroy historical information. Removing an object without recording where it was found may preserve the object itself while erasing evidence that could help explain its purpose and origin.
A treasure that changes our understanding of the past
The Singen hoard is not a legendary chamber overflowing with gold. It consists of 11 silver coins whose significance lies in their rarity, their shared archaeological context and the questions they raise about life in ancient central Europe.
The identity of the person who buried them remains unknown. So does the precise reason they were concealed. There is no verified evidence that a much larger treasure remains hidden beneath the former sports field.
What researchers do have is something more useful than speculation: physical evidence that can be studied, compared and placed within a wider historical landscape.
More than 2,000 years ago, someone gathered these coins and concealed them. Centuries of cultivation spread them through the soil, while the world above changed beyond recognition. Eventually, archaeological investigation brought them back together.
The discovery reminds us that history does not always emerge from royal tombs, monumental ruins or famous battlefields. Sometimes, it begins with a handful of silver coins beneath an ordinary patch of ground.
And the most intriguing question may never be how much the coins were worth. It may be what happened to the person who left them behind.
