Centuries-Old Irish Marriage Locket Containing Rare Italian Gold Coin Exceeds Expectations at London Auction

A remarkable silver locket crafted in 1660 to commemorate the wedding of two prominent Catholic landowners in County Cork, Ireland, has captured the attention of historians, collectors, and numismatists alike. Lost to history for centuries before its accidental rediscovery by a farm laborer in the nineteenth century, the intricate piece of seventeenth-century jewelry recently made its way to the auction block at Roseberys in London. Featuring a rare and beautifully preserved gold coin securely sealed within its silver casing, the artifact vastly outperformed its pre-sale estimates, underscoring its profound historical value, rarity, and unique provenance.

The story of the locket begins during a turbulent era in Irish history. Fashioned around 1660, the oval-shaped silver keepsake was created to celebrate the union of Robert Coppinger and his wife, Margarett, whose maiden name was Roche. As members of the Catholic landowning gentry in County Cork, the couple navigated a complex social and political landscape. Their commitment to their faith and their new life together is immortalized on the exterior of the locket itself. The front of the silver casing is adorned with a detailed engraving depicting the Nativity, a deeply significant Christian motif. Meanwhile, the reverse side features an equally intricate engraving illustrating the Adoration of the Magi. Alongside this sacred imagery, the locket bears the clear inscription of the couple’s names: "ROBT COPPINGER & MARGARETT COPPINGER als. ROCHE," providing an undeniable personal link to the individuals who commissioned and wore it over three and a half centuries ago.

However, the physical craftsmanship and sentimental value of the locket extend far beyond its engraved exterior. Upon opening the silver casing, historians and conservationists discovered an extraordinary hidden treasure: a gold 2 doppia coin minted in 1619 during the reign of Duke Ranuccio I Farnese in the Italian territories of Parma and Piacenza. According to specialists at Roseberys, the inclusion of this specific high-value foreign coin carried a special resonance for the Coppinger family. During the seventeenth century, wealthy Europeans frequently carried high-value currency as portable wealth and jewelry, utilizing circulating doppias as trade gold. For a Catholic landowning family in Ireland, possessing such a coin blended personal devotion, economic security, and international commerce into a single, wearable object of art.

Despite its deep personal and historical significance, the locket eventually vanished from the family’s possession, entering a long period of obscurity. The precise circumstances surrounding its loss—whether it was misplaced during a period of conflict, hidden for safekeeping, or accidentally dropped—remain unknown. For generations, the silver keepsake rested quietly beneath the soil, shielded from the passage of time until around 1850.

The rediscovery of the locket occurred near the historic castle of Mashanaglass in County Cork, where a local farm laborer was working the land. As the worker struck the earth with his spade, he unexpectedly uncovered the historic artifact. Unfortunately, the violence of the agricultural tool left its mark, striking the exterior of the locket and inflicting visible damage upon the silver casing. Yet, in a remarkable twist of fate, the coin sealed safely inside remained entirely untouched. As experts at Roseberys noted, the survival of the 1619 gold doppia is directly owed to the locket that housed it, which acted as a protective shield against the very spade that unearthed it nearly two centuries ago.

Following its dramatic unearthing in the mid-nineteenth century, the locket was brought to the local parish rector. Recognizing the importance of the find, the rector oversaw its restoration before returning the heirloom to a descendant of the Coppinger family. Anna Evans, Head of Works of Art at Roseberys, reflected on the rare and evocative nature of the survival, explaining that very few historical objects manage to endure across the centuries while retaining such a vivid, tangible sense of the specific people and places to which they originally belonged.

When the artifact finally arrived at Roseberys for the Fine & Decorative auction on October 1, it was presented not merely as a standalone piece of jewelry, but as the centerpiece of a richly documented historical archive. The auction lot included a copy of The Cork Historical and Archaeological Society Journal from 1895, which originally reported on the incredible mid-century discovery of the locket at Mashanaglass. Furthermore, the sale package was accompanied by a handwritten letter dating back to 1892, penned by the Keeper of Coins at the British Museum, in which the official formally identified and authenticated the Italian gold coin nestled within.

Beyond its deeply personal provenance and the fascinating narrative of its recovery, the locket gained immense appeal among numismatists due to the extreme rarity of its internal contents. Surviving examples of the 1619 2 doppia are exceedingly scarce today, largely because historical gold coinage of this type was frequently melted down, re-minted, or lost to circulation over the centuries. When authentic specimens from this specific year do appear on the market, they typically surface at major international sales and command exceptionally high prices.

This particular doppia fully lived up to its elite numismatic reputation when it crossed the auction block at Roseberys. Entering the sale with a pre-estimate ranging between £3,000 and £5,000, the lot quickly attracted competitive bidding from collectors eager to acquire a piece of such undeniable historical and material importance. As the gavel finally fell, the locket and its hidden treasure realized a final sale price of £8,528, comfortably surpassing its initial expectations.

The journey of the Coppinger-Roche locket—from its creation in 1660 as a symbol of matrimonial devotion, through its loss and dramatic unearthing beneath the shadow of Mashanaglass castle, to its eventual documentation by nineteenth-century scholars and its successful modern auction—stands out as an exceptional chapter in material history. As Roseberys specialists observed, it is exceedingly rare to encounter a historical coin whose complete journey, stretching directly from the mint to a marriage keepsake and onward to its accidental rediscovery, remains so thoroughly preserved and well-documented.
