Authentication Indicators
The presence of a stamped '830' purity mark is consistent with continental European silver standards, though further testing via XRF or acid is needed for absolute verification.
Origin & Manufacturing
Likely Scandinavian, Danish, Norwegian, or German origin, regions historically known for widespread adoption of the .830 silver standard.
Era & Period
Likely 20th Century, given the use of numeric fineness stamping rather than traditional Victorian or Georgian hallmarks.
Age Estimate
Circa 1900-1950, based on the standard 830 numerical fineness marking convention common in early-to-mid 20th-century continental Europe.
Cultural Significance
Reflects the standard regulatory marking practices of European silversmithing guilds and governments during the late 19th and early 20th centuries.
Condition Notes
The base shows moderate surface scuffing, scratches, and a layer of dust or tarnish typical of handling and storage. Overall structure appears intact.
Value Estimate
Valued primarily on melt weight of the .830 silver content plus a modest collector or decorative premium, typically ranging from $50 to $150 depending on total weight and exact maker.
Care & Maintenance
Clean gently with a soft microfibers cloth and specialized silver polish formulated for low-abrasion care. Store in a tarnish-resistant bag or dry environment.
