Doppelvierer Coin: Rare 15th Century Silver of Basel

Illustrated Specimen Details: Doppelvierer

Example Specimen: Doppelvierer, 15th century — City of Basel (Switzerland)

This rare silver specimen represents the 15th-century coinage of the Free City of Basel. The obverse features the inscription MON ETA BAS ILIE (abbreviation for Moneta Basiliensis), surrounding a long cross that divides the field into four distinct quadrants — a hallmark of medieval European design.

The reverse displays the coat of arms of Basel — the iconic bishop's staff (Baselstab) — set within an elegant quatrefoil. The religious legend GLORIA IN EXCELSIS D (Glory to God in the highest) encircles the central design. Interestingly, while most catalogs record the variant "EXCELSI", this particular die maintains the full "EXCELSIS", marking it as a notable orthographic variety of the Gothic period.

1. SWISS CANTONS (City of Basel, City of Laufenburg...; 16th-17th centuries): doppelvierer = 8 kreuzer = 2 vierer = 1/60 dicken
2. AUSTRIAN STATES (Landgraviate of Upper Alsace...; 16th century): doppelvierer = 8 kreuzer = 2 vierer
3. GERMAN STATES (City of Freiburg...; 16th century): doppelvierer = 8 kreuzer = 2 vierer
4. FRENCH REGIONAL ISSUES (Free imperial City of Colmar, City of Thann...; 15th-17th centuries): doppelvierer = 8 denier = 2 vierer

Historical Overview of the Doppelvierer

Etymology: The term doppelvierer literally translates from German as "double four." It originates from the vierer (a coin worth four units). The name follows the common medieval Germanic logic of naming denominations based on their numerical value.

The doppelvierer was a silver denomination primarily circulated in Upper Germany, Austria, and the Swiss Cantons during the late medieval and early modern periods. Its value was typically equivalent to 8 smaller units — such as the kreuzer or the denier. In the Swiss monetary system, it served as a practical fractional coin, being 1/60 of a silver dicken.

The Rappenmünзbund and Regional Stability

Basel was a leading member of the Rappenmünzbund (Rappen Mint Federation), a monetary union established in 1403 to standardize silver coinage along the Upper Rhine. The doppelvierer was a key product of this union, facilitating trade between Basel, Freiburg, Colmar, and other member cities. Because of this union, the designs of these coins often look remarkably similar across different issuers, featuring either the long cross or regional heraldry.

The 15th-century variants, like the one illustrated above, are characterized by their deep Gothic aesthetics. The legends were engraved in "Blackletter" script, which gradually gave way to Roman lettering in the 16th century. Collectors often distinguish between these eras by the transition in typography and the refinement of the heraldic bishop's staff.

Varieties and the "Excelsis" Mystery

One of the most engaging aspects for numismatists is the study of legend variations. Due to the manual nature of die-cutting in the 1400s, minor differences in spelling were common. The legend Gloria In Excelsis Deo was often truncated to fit the circular flan. While "EXCELSI" is the standard abbreviation found in many catalogs, the appearance of the full "EXCELSIS" (as seen in this specimen) suggests a high-quality production or a specific minting series that didn't compromise on the Latin grammar.

Interestingly, the influence of the "vierer" naming convention even reached the Hungarian filler coin, which earned its name because of its initial equality to four local kreuzers, demonstrating how Germanic numismatic terminology spread throughout the Habsburg territories.
