Gold Type
None (Faux Gold/Base Metal Alloy). The surface appears to be a painted or chemically patinated finish over a non-gold substrate.
Weight
Unknown; likely 500g-1000g if made of lead/zinc, but significantly lighter if resin. It lacks the density-to-volume ratio of a genuine 1kg gold bar.
Description
A trapezoidal simulated gold ingot featuring 'Bank Sumatra' branding. The piece is designed to mimic an aged bullion bar with raised lettering, a serial number box, and purity markings. Its aesthetic is rugged and 'found treasure' style, often used for stage production, escape rooms, or themed decor.
Key Features
Raised 'AU' (Gold chemical symbol) logo, five-star constellation design, and a recessed serial number field. The high-relief '999.9' at the base is a primary decorative feature.
Color & Finish
Antique bronze-gold tone with heavy faux patina. The finish is uneven with high-contrast darkening in the recessed areas to simulate age. Surface is porous and textured.
Hallmarks & Stamps
Faux hallmarks include: 'BANK SUMATRA' circular seal with 'AU', five raised stars, a serial number '0410824', and a purity stamp '999.9'. These are cast into the mold rather than struck.
Dimensions Estimate
Approximately 15cm x 5cm x 4cm; consistent with the 'Good Delivery' bar shape but scaled down for display.
Gemstones & Inlays
None. Feature set consists of raised relief molded text and symbols.
Clasp & Closure
Not Applicable.
Chain & Links
Not Applicable. The edge finishing is rough with visible mold seam lines characteristic of casting.
Craftsmanship Details
Rough sand-casting or mold-pouring. The lettering has rounded edges and the field of the bar is uneven, indicating a low-precision manufacturing process.
Authentication Indicators
RED FLAGS: The texture is excessively grainy; genuine 999.9 gold is smooth and lacks surface pitting. Hallmarks are part of the cast rather than stamped in. The 'Bank Sumatra' refers to a fictional or historical entity not currently producing tradeable bullion.
Origin & Maker
Likely Southeast Asia (indicated by 'Sumatra' text) but manufactured as a novelty/movie prop or decor item. Unaffiliated with a known mint.
Era & Period
Contemporary (Modern Prop). Designed with a 'Vintage/Historical' aesthetic meant to look like early 20th-century colonial bullion.
Age Estimate
Modern production (Last 10-20 years). The wear is simulated rather than natural oxidation.
Cultural Significance
Represents the 'Gold Rush' and colonial treasury aesthetic. It reflects the mystery associated with hidden Southeast Asian gold hoards and 'Yamashita's Gold' legends.
Condition Notes
Fair to Good (Novelty grade). The surface shows intentional scuffing and paint wear to reveal darker 'oxidized' layers. Lacks the crisp edges of professional bullion.
Value Estimate
$15 - $40 USD as a novelty or decorative item. It has no intrinsic melt value as it contains no measurable gold content.
Care & Maintenance
Wipe with a dry cloth. Do not use gold cleaners or abrasives as they will strip the faux gold paint/finish.
Similar Items
Plastic or resin movie props, brass-plated paperweights, and genuine historical cast bars (which would have significantly more precise assay marks).
Interesting Facts
In the world of collectibles, 'bank bars' from non-existent or defunct regional banks are common movie props. Sumatra is famous for gold mining (the 'Island of Gold'), but they do not produce bars with this specific iconography.
