Venetian Grosso (Matapan)

The Venetian Grosso, popularly nicknamed the matapan, was a high-quality silver coin issued by the Republic of Venice from the late 12th century into the 14th century. Struck from nearly pure silver, it became one of the most trusted trade coins of the medieval Mediterranean and helped anchor Venice's commercial dominance in the Levant.

The design is highly formulaic and instantly recognizable. One face shows two standing figures: the Doge of Venice receiving a banner or staff from Saint Mark, the city's patron. The other face shows Christ enthroned, holding a Gospel book. The example photographed here shows these characteristic standing and seated figures with clear religious iconography on both sides.

Because the type stayed visually consistent across many successive doges, individual coins are usually attributed by the Doge's name in the obverse legend rather than by any change in the imagery.

Venice introduced the Grosso around the 1190s, traditionally under Doge Enrico Dandolo, as international trade demanded a reliable, high-value silver piece larger than the small pennies (denari) then in circulation. Its consistent weight and fine silver made it a standard unit for commerce with Byzantium and the eastern Mediterranean.

The iconography deliberately echoed Byzantine models: the enthroned Christ recalls the figures on Byzantine gold and silver coinage, signaling that the Grosso was meant to compete in the same trade networks. The Doge-and-Saint-Mark scene asserted Venetian civic and religious identity on a coin used far beyond the lagoon.

The Grosso circulated for roughly a century and a half before debasement, changing bullion values, and the rise of the gold ducat gradually reduced its role. Later doges issued Grossi of varying weight and fineness, and production of the classic type wound down during the 14th century, though the design influenced later Venetian and imitative coinages around the Adriatic and Aegean.

Look for a small, thin silver coin, typically around 20–22 mm in diameter and roughly 2 grams, struck in high-purity silver that often survives with a bright or lightly toned surface. The flan is usually slightly cupped or dished, a legacy of the Byzantine-inspired striking style.

The defining feature is the pair of standing figures on one side — the Doge on the left holding a long staff or banner, and Saint Mark on the right, with a vertical inscription running between them. The opposite side shows Christ seated on a throne facing forward, holding a book, flanked by abbreviated Greek-style religious lettering (often IC XC).

Attribution to a specific Doge relies on reading the Latin legend beside the Doge's figure, which names the ruler; the saint's side typically reads S · M · VENETI (Saint Mark of Venice). Because the imagery repeats across reigns, the legend is the key to dating an individual coin.

As a genuinely medieval silver trade coin with strong historical appeal, the Grosso is collectible but not rare in absolute terms — many thousands survive. Common doges in worn or average condition are generally affordable entry points into medieval coinage, while sharp, well-centered, high-grade examples and scarcer or short-reigned doges command clear premiums.

Condition, centering, and full legibility of the legend (which identifies the Doge) drive value more than the type itself. Bright original silver with complete inscriptions is worth substantially more than corroded, clipped, or off-center pieces.

Because values swing widely by Doge, grade, and eye appeal, treat any single figure with caution and compare recent auction results for the same Doge and condition rather than relying on a catalog headline price.
