Type
Counterfeit Numismatic/Novelty Coin
Purity
Non-gold; 0K. Appears to be base metal (brass/steel) with a worn, non-precious wash.
Gold Type
Gold-tone coating over base metal; exhibits significant oxidation and rust.
Weight
Estimated 3.5-4.5 grams (Standard Japanese 50 yen is 4g Ni-Cu; this piece appears cast and potentially lighter or heavier depending on alloy).
Description
This item is a degraded imitation of a Japanese 50 Yen coin, erroneously presented as a gold item. It features the characteristic central hole and paulownia flower motifs, but the heavy oxidation, pitting, and 'rust' are definitive indicators that the item contains no gold content, as gold does not oxidize or produce orange rust.
Key Features
Central hole (ana-aki), stylized paulownia flowers, and degraded Japanese script. Significant iron-oxide (rust) staining.
Color & Finish
Dull greyish-silver to brassy base metal with heavy brown/orange oxidation (rust) and encrustation.
Hallmarks & Stamps
Imitation Japanese characters and design features resembling a 50 Yen coin; no legitimate gold hallmarks.
Dimensions Estimate
Diameter approx. 21mm (standard 50 Yen size); flat profile with central hole.
Gemstones & Inlays
None; surface is encrusted with environmental debris and corrosion products.
Clasp & Closure
None; smooth edge (non-reeded visible).
Chain & Links
N/A; singular coin-shaped object.
Craftsmanship Details
Poor quality; likely a cast imitation with blurred relief and uneven surfaces, lacking the precision of a government-minted strike.
Authentication Indicators
Strong Red Flags: Presence of orange/brown rust (iron oxide) is impossible for gold. Pitting and flaking reveal a base metal core. Design details are mushy, consistent with casting rather than striking.
Origin & Maker
Unknown counterfeit or novelty manufacturer; mimicking Japanese coinage.
Era & Period
Modern period (post-1967 design style); imitator of the Showa/Heisei era 50 Yen coin.
Age Estimate
Uncertain; design mimics coins minted since 1967, but corrosion suggests poor storage over the last 10-30 years.
Cultural Significance
Represents the common practice of creating 'lucky' gold-colored charms or low-quality counterfeits of high-circulation currency.
Condition Notes
Poor/Damaged. Extensive corrosion, pitting, surface loss, and environmental encrustation. Structural integrity is compromised.
Value Estimate
Zero bullion value. Negligible numismatic value due to being a counterfeit in poor condition.
Care & Maintenance
Not recommended for investment; clean with mild soap only to prevent further disintegration, though the item holds no bullion value.

Interesting Facts
Authentic Japanese 50 Yen coins are made of cupronickel (75% copper, 25% nickel), not gold. The central hole was originally added to distinguish it from the 100 yen coin.
