Historical Context: This 1858 2 1/2 Silbergroschen was issued by the Grand Duchy of Oldenburg, a state within the German Confederation. Although the coin type is associated with Paul Frederick August, the reigning Grand Duke was Peter II (1853-1900). Oldenburg, a Grand Duchy since 1815, maintained sovereignty within the German Confederation. The Silbergroschen denomination integrated Oldenburg into the North German monetary system, standardizing currency for regional commerce before unification.
Artistry: The coin's design follows Neoclassical or early Historicist styles, common for mid-19th century German coinage. The obverse typically presents a dignified bust portrait of Grand Duke Peter II, or his crowned monogram, rendered with realistic yet idealized features. The reverse displays the "2 1/2 SILBERGROSCHEN" denomination and "1858" date, often framed by a wreath or simple border, alongside the issuer's legend. The specific engraver for this fractional issue is generally unattributed, reflecting standard minting practices.
Technical/Grading: Struck in billon (.375 silver), this 21 mm, 3.22 gram coin exhibits characteristic technical qualities. High-points prone to wear include the Grand Duke's hair and facial features, and central denomination elements. Due to the softer billon alloy and mass production, strikes often show weakness, particularly on peripheral legends or fine details. Collectors may also find typical planchet imperfections like minor laminations or flan cracks, common for this type.
