Divers working off the coast of Caesarea, Israel, have pulled hundreds of silver and bronze coins from two separate shipwrecks on the Mediterranean seabed, according to the Israel Antiquities Authority (IAA). The coins date to the mid-third century of the Roman era, making them roughly 1,700 years old. A second cache of about 560 Mamluk-period silver coins, roughly 600 years old, surfaced from one of the sites, along with a rare bronze ring depicting the Good Shepherd, an early Christian symbol. The finds raise pointed questions about how and why two vessels came to rest so close together, and whether the wrecks share a common cause.
Why the Caesarea coin haul demands closer scrutiny
Two shipwrecks sitting near each other off the same ancient port city are not, by themselves, unusual. Caesarea served as a major Roman harbor, and centuries of maritime traffic left debris across the seabed. What makes this discovery different is the combination of dating, cargo type, and proximity. The Roman-era wreck yielded hundreds of mid-third-century silver and bronze coins, as described in Washington Post coverage, while the second site produced a large batch of Mamluk-period silver coins numbering about 560. The two cargoes are separated by roughly a thousand years, yet they were found in the same stretch of seafloor during routine inspections after winter storms shifted sand cover.
That timing detail matters. Storms expose buried material that can deteriorate or scatter once it is no longer sealed under sediment. IAA divers were reportedly surveying the area after seasonal weather when they noticed artifacts protruding from newly scoured patches of seabed. Jacob Sharvit, an official with the IAA’s maritime archaeology unit, has been central to the recovery effort. Robert Kool, head of the IAA coin department, confirmed that the Roman pieces cluster in the mid-third century, a period of political instability and frequent military campaigns across the empire. If the Roman coins came from a single cargo, they could reflect a military payroll shipment or a merchant consignment moving along established trade routes. If they came from multiple sources mixed together by centuries of seabed movement, the archaeological picture changes sharply.
A working hypothesis worth testing is whether the two wrecks represent a single storm event that struck a convoy or successive ships on the same route. The mid-third century saw repeated economic crises and coin debasement across the Roman world, and large shipments of silver would have been high-value targets for both pirates and storms. Even in the later Mamluk period, heavily laden merchantmen would have been vulnerable as they approached or left Caesarea’s exposed anchorage. Comparing die-linked coin batches and sediment layers between the two sites could confirm or rule out a shared sinking event, but that analysis depends on primary field data that the IAA has not yet released in full.
Other scenarios remain plausible. The Roman vessel may have gone down in a localized squall, its cargo settling into a depression that later attracted wreckage from a different era. Alternatively, long-term coastal processes could have moved material from distant wrecks into the same general zone. Without published maps of artifact distribution, it is difficult to distinguish between a single catastrophic episode and a palimpsest of multiple losses.
Coins, a ring, and the limits of what the IAA has shared
The strongest physical evidence centers on three categories of objects. First, the Roman-era silver and bronze coins, described by the IAA as numbering in the hundreds and dating to the mid-third century. Second, the Mamluk-period silver coins, totaling about 560, which come from a much later era of Mediterranean commerce and Islamic rule in the region. Third, the Good Shepherd ring, a small bronze piece showing a young shepherd carrying a sheep on his shoulders, a motif closely tied to early Christian iconography.
The ring stands out because it connects the Roman-era wreck to the religious culture of its time. Early Christian symbols were not yet dominant in the third century, and finding one aboard a merchant or military vessel suggests the ring belonged to an individual rather than forming part of a commercial cargo. That personal dimension adds texture to what is otherwise a story about bulk coinage. It hints at passengers or crew whose beliefs differed from the official religious practices of the Roman state, and whose possessions sank with them when the ship went down.
Sharvit and Kool are the two IAA officials who have spoken publicly about the finds. Sharvit, whose role covers maritime archaeology, has framed the haul as a window into Mediterranean trade patterns and the dangers of navigating near Caesarea’s reefs. Kool’s coin department provided the dating that places the Roman pieces in the mid-third century and the later hoard in the Mamluk period, emphasizing the rarity of such well-preserved assemblages. Their statements, relayed through international reporting, remain the only named, on-the-record accounts of the discovery. No direct statements from the divers who physically recovered the coins have appeared in available coverage, and no independent archaeological teams have yet examined the sites.
The absence of a full IAA excavation report limits what outside researchers can verify. No GPS coordinates for either wreck, no stratigraphic profiles of the sediment layers, and no metallurgical analysis of the coins have been made public. The aggregate count of “hundreds” for the Roman coins is the most specific figure available, and it leaves open questions about exact quantity, denomination mix, and mint origin. Likewise, the Mamluk hoard has been described in broad numerical terms rather than through a detailed catalogue. Until those data appear, interpretations of the cargoes’ purpose and routes will remain provisional.
Open questions about storm timing and cargo origins
Several gaps in the evidence prevent a firm conclusion about what happened to these ships. The most pressing is whether the Roman-era coins came from one vessel or were scattered across the seabed from multiple wrecks over time. Die-link analysis, which compares the stamps used to strike individual coins, could determine whether a batch was minted together and shipped as a unit. That work has not been reported, nor has any discussion of wear patterns that might distinguish freshly issued pay from older circulation pieces.
A second unresolved question involves the relationship between the Roman and Mamluk finds. The two caches are separated by roughly a millennium, and their proximity could be coincidental. Caesarea’s harbor attracted ships across many centuries, and wrecks from different eras can end up in the same general zone as coastlines shift and storms redistribute sediments. On the other hand, if both wrecks lie within a narrow corridor aligned with known approaches to the ancient port, that might point to a persistent navigational hazard that claimed victims in different periods.
There is also the matter of what, beyond coins and the ring, may still lie buried. Reports mention additional artifacts such as metal fittings, but without an inventory it is impossible to assess whether the vessels were primarily cargo carriers, troop transports, or mixed-use ships. Hull remains, if present, could reveal construction techniques and help narrow the ships’ places of origin. Organic materials like wood and textiles often survive in anoxic pockets under the seabed; if such contexts exist here, they have not yet been described.
For now, the Caesarea discoveries highlight both the promise and the constraints of underwater archaeology conducted under storm-driven time pressure. Divers must secure exposed objects quickly before they are looted or damaged, often ahead of full documentation. The IAA’s decision to publicize the finds early has brought global attention to the site, but it has also foregrounded how much remains unknown. Until detailed scientific reports are released, the Roman coins, the Mamluk hoard, and the solitary Good Shepherd ring will continue to pose more questions than they answer about the ships, their crews, and the waters that claimed them.
