Simulated Gold or Brass Circular Planchet/Slug

Type

Misc (Possible Token, Planchet, or In-lay)

Purity

Estimated 0K / Non-Gold. Visible surface indicates possible brass, copper, or steel with base-metal oxidation.

Gold Type

None (Yellow-toned base metal)

Weight

3 to 7 grams (estimated based on size and base metal density)

Description

This item appears to be a flat, circular metallic slug or blank. While it has a yellow-tone core visible through surface abrasions, the heavy blue-grey oxidation on the surface is a strong indicator of base metal (like brass or copper-nickel) rather than fine gold, which would remain chemically inert and untarnished.

Key Features

Raised outer rim; blank field; significant surface scratching; blue/purple chemical patina.

Color & Finish

Heavily tarnished metallic grey with iridescent blue-purple oxidation; reveals yellow brassy tones under scratches.

Hallmarks & Stamps

None visible. The item is blank/unmarked on the visible face.

Dimensions Estimate

Approximately 20mm to 25mm in diameter (similar to a US Quarter).

Gemstones & Inlays

None.

Clasp & Closure

N/A.

Chain & Links

N/A.

Craftsmanship Details

Basic machine-stamped or lathed disc with a simple raised rim and flat interior field.

Authentication Indicators

Red Flag: Iridescent blue/purple oxidation is characteristic of base metals, not gold. Deep scratches show a non-lustrous yellow underneath, suggesting brass.

Origin & Maker

Unknown; likely industrial or a blank for decorative use.

Era & Period

Modern (Undeterminable from blank surface).

Age Estimate

Likely 1-20 years based on surface oxidation and mechanical scratching.

Cultural Significance

None.

Condition Notes

Poor/Damaged. Extensive scratching, heavy tarnish, and signs of environmental exposure.

Value Estimate

Nominal/Melt value only ($0.05 - $0.10). No significant gold content detected visually.

Care & Maintenance

If brass, can be cleaned with mild acid or polish; if gold-plated, aggressive cleaning will remove the thin gold layer. High-quality gold would not require this level of maintenance.

Similar Items

Brass washers, arcade tokens, or coin-room planchets.

Interesting Facts

Blanks like this are often used in manufacturing jewelry settings, tokens, or as mechanical spacers. Gold items are almost never left this roughly finished unless they are refined scrap.
