Description
A circular metal token featuring a center hole and scrolled decorative patterns mimicking East Asian currency. The item displays catastrophic failure of its gold-toned surface, revealing a non-precious core that is actively corroding.
Key Features
Central circular puncture, arabesque scroll motifs, and fraudulent gold coloration used to mimic high-carat bullion.
Color & Finish
Severely degraded yellow gold plating with extensive brown, orange, and grey oxidation of the base metal core
Hallmarks & Stamps
No official purity marks; stylized Japanese characters are present but obscured by corrosion
Dimensions Estimate
Circa 20-22mm diameter (similar to a US Nickel or Japanese 50 Yen coin)
Gemstones & Inlays
None
Clasp & Closure
None (Solid disc with central hole)
Chain & Links
Smooth, non-reeded edge typical of modern tokens or low-value circulating coinage
Craftsmanship Details
Low-quality industrial stamping. The plating was likely applied via electrocapillary action but lacks an adequate nickel barrier, leading to the rapid migration of base metal oxides to the surface.
Authentication Indicators
RED FLAG: Gold does not rust or produce brown/orange flake oxidation. The peel-off nature of the color and the base metal corrosion confirm this is not solid gold.
Origin & Maker
Likely a novelty manufacturer or counterfeit producer in East Asia
Era & Period
Modern / Late 20th Century
Age Estimate
Circa 1980-2010 based on degradation characteristics
Cultural Significance
Represents the widespread production of 'luck coins' and 'temple tokens' which are often plated to look like gold for ceremonial use, though sometimes sold deceptively as bullion.
Condition Notes
Poor (Salvage Grade). Significant surface pitting, oxidation, and loss of plating. The presence of rust-colored corrosion indicates a high iron or steel content.
Value Estimate
Zero intrinsic melt value. Nominal value only as a novelty or reference for what counterfeit gold corrosion looks like.
Care & Maintenance
Not applicable as a precious metal; item has zero gold value and is structurally compromised by rust.

Interesting Facts
Real gold coins like the Japanese 'Koban' were made of high-purity gold and do not corrode, making this a useful educational piece for identifying 'fools gold' or plated fakes.
