Cast Small Silver Bullion Ingot
Coin/Bullion · Unknown private refinery or silversmith workshop. The piece lacks visible commercial branding commonly seen on 'Engelhard' or 'Johnson Matthey' bars, suggesting a smaller local refiner or a hand-poured custom piece.
Pattern: Generic Cast Bar Pattern; non-standardized. These are typically produced for weight value rather than aesthetic collection value.
Type
Coin/Bullion
Maker
Unknown private refinery or silversmith workshop. The piece lacks visible commercial branding commonly seen on 'Engelhard' or 'Johnson Matthey' bars, suggesting a smaller local refiner or a hand-poured custom piece.
Material
Likely Silver (.800 to .999 purity). Common compositions for such small bars include Sterling (.925) or Fine Silver (.999). Without a stamp, a density or acid test is required.
Dimensions
Estimated small form factor: approximately 30-40mm in length. Estimated weight: between 1/2 troy ounce and 1 troy ounce (15g to 31.1g) based on hand-scale.
Description
This is a small, cast silver bar or ingot, characterized by its industrial, unrefined aesthetic. Unlike minted bullion with sharp edges and mirror finishes, this piece shows the organic textures of molten metal cooling in a mold. Its value is derived almost entirely from its precious metal content rather than artistic merit.
Key Features
Rounded corners, irregular surface texture, presence of sulfur-based tarnish (dark spotting), and a lack of standardized industrial markings.
Material & Composition
Likely Silver (.800 to .999 purity). Common compositions for such small bars include Sterling (.925) or Fine Silver (.999). Without a stamp, a density or acid test is required.
Finish & Decoration
Natural cast finish with heavy surface oxidation and tarnish. The surface shows 'cooling ripples' and a matte, porous texture typical of sand or graphite mold casting. No decorative engraving is visible.
Hallmarks & Stamps
No visible hallmarks or purity stamps in the provided image. Many small custom-poured bars are 'unmarked,' which often requires professional assaying to confirm metal content.
Construction Details
Open-faced mold cast. The rectangular form with rounded, irregular edges indicates the molten metal was poured and allowed to cool in a simple mold. Hand-made characteristics.
Functional Features
Investment vehicle or raw material for jewelry making. No mechanical features or moving parts.
Handle & Grip Details
N/A; item is a solid rectangular ingot.
Craftsmanship Details
Rudimentary. This is a functional object of utility rather than fine art. The edges are not trimmed or polished, indicating a 'pour and cool' method with little post-production work.
Authentication Indicators
The tarnish pattern is consistent with silver sulfide (the way silver reacts to air). However, the lack of hallmarks is a significant red flag; it could be a base metal (lead/tin) with a silver wash. Heavy wear-testing or an XRF scan is necessary.
Origin & Manufacturing
Country of origin unknown. Often produced by small-scale hobbyist refiners or local jewelry workshops to consolidate scrap silver metal.
Era & Period
Contemporary/Modern era. While it mimics historical 'cob' or bar forms, it is likely a modern secondary-market refining product.
Age Estimate
Likely produced within the last 20-30 years based on the shallow oxidation and general form, though its 'primitive' look is a result of the casting method rather than age.
Cultural Significance
Represents the fundamental form of silver as a store of value. Historically, bars like this were used for trade and raw materials before being struck into currency.
Condition Notes
Fair. The piece shows significant tarnish, surface pitting, and contact marks. As a bullion item, these surface flaws do not significantly detract from its metal melt value but remove it from 'collector grade' status.
Value Estimate
Spot price of silver for the estimated weight. At current markets, roughly $15.00 - $30.00 USD depending on verified weight and daily market fluctuations.
Care & Maintenance
Minimal maintenance required as it is and investment piece. If desired, a silver dip or a soft cloth with rouge can remove tarnish, but for simple bullion, this is often unnecessary.
Similar Pieces

Interesting Facts
Hand-poured silver bars are increasingly popular in the 'silver stacking' community because each piece is unique due to the cooling process, creating 'fingerprints' of metal ripples.
