Gold-Plated Base Metal Blank or Slug
Raw Gold / Manufacturing Blank · Yellow Gold plating over a grey/silvery base metal alloy (likely steel, nickel, or lead-based).
Purity: Indeterminate; likely thin gold plating or flash (less than 0.1 microns). The core is clearly a non-gold base metal.
Type
Raw Gold / Manufacturing Blank
Purity
Indeterminate; likely thin gold plating or flash (less than 0.1 microns). The core is clearly a non-gold base metal.
Gold Type
Yellow Gold plating over a grey/silvery base metal alloy (likely steel, nickel, or lead-based).
Weight
Estimated 10-25 grams depending on thickness and core density. The heavy discoloration suggests the majority of the weight is non-precious.
Description
A circular disc featuring a two-tone appearance. The central flat plane exhibits a dull grey, metallic luster with horizontal abrasions, while the raised or outer rim shows a thin layer of yellow metallic coating. The item lacks the reflectivity, density, and color consistency of solid gold.
Key Features
Exposed base metal core; two-tone contrast between the grey interior and yellow exterior; circular geometry.
Color & Finish
Brushed or rough-sawn grey central face with a thin perimeter of dull yellow gold-tone; matte, unpolished, and heavily scratched surface.
Hallmarks & Stamps
None visible. The absence of marks on a flat surface is a strong indicator of a non-precious industrial or replica item.
Dimensions Estimate
Approximately 25mm to 35mm in diameter; 2mm to 4mm in thickness.
Gemstones & Inlays
None present.
Clasp & Closure
None; flat edge finishing suggesting a slug or component blank.
Chain & Links
Not applicable; solid disc construction.
Craftsmanship Details
Basic industrial stamping or sawing. The edges are rough and the surface finish is purely functional with no aesthetic refinement.
Authentication Indicators
Red flags: The exposed grey interior is a definitive indicator that the item is not solid gold. Real gold is consistent in color throughout its cross-section. The scratching reveals a harder, non-malleable base metal.
Origin & Maker
Unknown; likely a mass-produced industrial blank or a novelty token blank.
Era & Period
Contemporary Industrial; no specific historical design era identified.
Age Estimate
Likely modern (within the last 20 years) based on the mechanical scratching and oxidation patterns.
Cultural Significance
None; this appears to be a utilitarian or industrial object rather than a piece of cultural or jewelry heritage.
Condition Notes
Poor to Fair. Heavy surface abrasions, deep scratches on the face, and significant loss of surface coating or plating along the edges.
Value Estimate
Negligible/Nominal. Melt value is negligible as the gold content is likely only at the molecular plating level. It carries no numismatic or jewelry premium.
Care & Maintenance
Minimal value; no specialized care required. Cleaning will likely further strip the remaining thin yellow coating.

Interesting Facts
Items like these are often used as 'slugs' for testing machinery, or as the base for cheap souvenir medallions before a final strike or heavy plating layer is applied.
