Gros - Philipp de Platea

Historical Context: This Gros was issued by Philipp de Platea, Bishop of Sion, during his episcopate from 1527 to 1529. This era was marked by the burgeoning Reformation and significant political instability across Europe. As a prince-bishop, Philipp de Platea held both spiritual and temporal authority over the Valais region, navigating complex relationships with the Swiss Confederates and the House of Savoy. His coinage, including this Gros, served as a crucial assertion of his sovereignty and facilitated local commerce.

Artistry: The engraver of this Gros remains anonymous, typical for regional mints of the early 16th century, reflecting a provincial late Gothic style. The design prioritizes clarity and legibility. Common iconography for Sion Gros of this era would feature the Bishop's personal arms, often quartered with the Bishopric's arms, possibly surmounted by a mitre, on the obverse. The reverse typically displays a prominent cross, often floriated, encircled by the bishop's title or mint mark, conveying both spiritual and temporal power.

Technical/Grading: Struck in billon, an alloy susceptible to wear and corrosion, this Gros typically exhibits varying strike quality. High-points prone to wear include the central elements of the coat of arms, the tips of the cross, and any details on the mitre. Due to early 16th-century minting practices and billon composition, planchets often show irregular shapes. Strikes can be uneven, leading to areas of weakness or flatness, particularly on legends or peripheral devices. A well-struck example with minimal wear and good metal quality is highly desirable.
