Type
Raw Gold / Industrial Bar segment
Purity
Indeterminate; signs of gold-plating or copper alloy (low 9K-14K or non-precious base)
Gold Type
Rose or Red Gold-toned alloy (high copper content visible)
Weight
Estimated 20-50 grams based on visible volume and density
Description
A rectangular metallic strip displaying a deep reddish-gold hue, characteristic of high copper alloys or rose gold plating over a base metal. The item shows significant surface abrasion and is coated in a waxy or organic white substance, resting on a coarse aggregate surface.
Key Features
High copper-toned surface, rectangular profile, significant pitting and residue presence
Color & Finish
Deep copper-red with significant surface oxidation and organic residue
Hallmarks & Stamps
None visible; surface is heavily weathered with no legible markings
Dimensions Estimate
Width approximately 20-30mm; thickness 3-5mm
Gemstones & Inlays
None; features organic white residue and possible mineral encrustation
Clasp & Closure
N/A - Non-jewelry industrial form
Chain & Links
N/A - Solid rectangular profile with flat edges
Craftsmanship Details
Machine-cut edges with industrial-grade finishing; lacks the refinement of jewelry or investment bullion
Authentication Indicators
Red Flag: Significant red-orange toning suggests high copper oxidation, potentially gold-plated copper or brass
Origin & Maker
Unknown; likely industrial or architectural salvage rather than minted bullion
Era & Period
Contemporary industrial or salvaged salvage material
Age Estimate
Modern (post-1950s) given the straight-edge mechanical shearing
Cultural Significance
Represents industrial use of gold-toned alloys in architecture or machinery
Condition Notes
Poor; surface heavily scratched, oxidized, and contaminated with foreign matter
Value Estimate
Dependent on purity; if base metal, negligible value; if 10K gold, approximately $30-$35 USD per gram
Care & Maintenance
Requires ultrasonic cleaning and chemical testing (XRF) to determine metallurgical composition

Interesting Facts
Rose gold gets its color from copper; if an item is too red, it often indicates a lower gold karat or simple copper-based alloy
