Secrets Surface Beneath the Shore in Season 13—What Did Oak Island’s Team Discover This Time?
Ancient Coin Discovery Sparks Excitement on Oak Island

In a dramatic turn on Lot 5 of Oak Island, the search for historical clues has yielded a tantalizing find: an ancient coin that may date back over 400 years. Marty Lagina, his nephew Peter Fornetti, and metal detection expert Katya Drayton were combing the shoreline between a mysterious rectangular feature and a rounded stone foundation when the breakthrough came.
“We’re hoping to find something interesting, something valuable—a clue,” Marty said as the team prepared their equipment. They focused on a stretch of disturbed soil left by a skid steer, scanning the area with metal detectors. It wasn’t long before Katya’s device began beeping urgently.
“There is definitely something over here,” Katya said, as she pinpointed the location. The excavation revealed a small metal object, which, upon cleaning, appeared to be more than a mere shard. Marty noted an unusual attachment on the piece, suggesting it warranted further scientific analysis.
The artifact was carefully bagged and sent to the Oak Island Laboratory for examination. Laird Niven and Emma Culligan conducted preliminary tests, confirming that the object was indeed a cast-iron pot, likely dating to the 1700s. Emma explained, “The high phosphorus content makes it brittle in cold climates, suggesting it predates the Industrial Revolution. This fits with cookware used in the 1600s and 1700s.”
While the pot was a significant find in its own right, the team’s attention quickly returned to the search for smaller, potentially more telling artifacts. South of the rounded feature on Lot 5, Katya and Marty continued metal detecting. The detector picked up another signal—nonferrous this time—beneath a rock. Careful excavation revealed a small, green-tinted object.
“I think it’s a coin,” Katya said excitedly. Marty agreed. The coin was unmistakably ancient, showing what appeared to be a cross and a green patina indicative of copper. Its shape and composition suggested it was a hammered coin, a style used before the widespread adoption of milled coins during the Industrial Revolution.

The discovery immediately drew attention from the broader Oak Island team. Marty called his father, Gary Lagina, to witness the find. “That is old,” Gary remarked as he examined the coin. “There’s writing around the edges, partly corroded, but definitely not a button. This is a coin, and it could date back to pre-1600s.”
Experts at the lab will conduct further analysis, including a CT scan to reveal more details. The irregular thickness and pure composition of the metal suggest the coin is exceptionally well-preserved for its age, adding to the intrigue. “Older metals were purer and more resilient,” Katya noted. “They don’t deteriorate like modern alloys. This coin could tell us a lot about who was here and when.”
The implications of the find are considerable. Previous excavations on Lot 5 have yielded Roman-era coins, authenticated through metallurgical testing, providing a glimpse into the possible historical significance of the site. The new coin adds another layer to the mystery, potentially linking Oak Island to European maritime activity centuries ago.
Rick Lagina, observing the excitement, said, “The coin gives us immense hope. Every artifact we uncover tells a story, and this one could be key in understanding the early activity on the island.” The team is optimistic that further analysis will shed light on the coin’s origins, possibly connecting it to other historic finds, such as Portuguese silver coins discovered on the island.
For Marty, Peter, and Katya, the day’s discoveries underscore the value of persistence and meticulous searching. “Katya nailed it with the metal detecting,” Marty said. “She knew right away this was nonferrous. We’ve been searching Lot 5 for clues, and this could be one of the most significant yet.”

The team plans to expand their excavation around the rectangular and rounded features, hoping to uncover additional artifacts that may contextualize the coin and the surrounding structures. The combination of metal detection, careful excavation, and laboratory analysis continues to provide a scientific backbone to the search, moving beyond speculation to verifiable discoveries.
With each artifact, Oak Island continues to reveal its layered history, blending mystery, science, and the thrill of discovery. The new copper coin may not only shed light on who visited the island centuries ago but also provide clues about the elusive “Money Pit” and the broader narrative of early exploration in the region.
As the team works methodically, the sense of anticipation is palpable. Each find, whether a cast-iron pot or a hammered coin, contributes to a deeper understanding of Oak Island’s past. “This is more than just finding objects,” Rick said. “It’s piecing together history, one clue at a time.”
For the Lagina team and their collaborators, Lot 5 has proven to be a treasure trove of insights, and the latest coin discovery offers a glimpse into the island’s rich, enigmatic past. Whether it ultimately helps unravel the full Oak Island mystery remains to be seen, but one thing is clear: the search is far from over, and each new find brings them closer to understanding the secrets hidden beneath the shore.
