Octagonal brass/bronze token or seal-like medallion with green patina

Octagonal brass/bronze token or seal-like medallion with green patina

Metalwork / Tokens / Exonumia
Uncommon
Identified on June 25, 2026

Estimated Value

$10-$50 as-is; potentially higher if identified as a scarce historical token or maker's piece

Small octagonal metal piece with a green verdigris patina, suggesting long-term oxidation of a copper alloy. The face shows a circular border and partial lettering around the perimeter; visible text appears to include fragments such as 'GIA...' and '...ER...E...' though the full inscription is not legible from the image. The center appears to have a worn emblem or device, but the design is too degraded to identify confidently. The object may be a token, seal, badge, or advertising piece rather than a coin, given its octagonal shape and lack of visible denomination or monarch portrait.

Era

Late 19th century to early 20th century (estimated)

Origin

Unknown; possibly Europe or North America

Material

Copper alloy (brass or bronze) with verdigris patina

Condition

Fair to Poor; heavily corroded/oxidized with significant surface wear and obscured details, but the stamped lettering and circular border remain partially visible

Authentication

Authenticity Score

Medium-Low; the object appears genuinely aged and oxidized, but the exact identity and period cannot be confirmed from the single image and the inscription is too worn to verify

Provenance

Unknown. The lettering suggests it may have been a commercial, organizational, or commemorative token; exact provenance cannot be determined from the image alone.

Historical Significance

If authentic and identifiable, pieces like this can reflect local commerce, fraternal organizations, advertising history, or commemorative practices from the late 19th/early 20th century. As shown, its historical significance is limited by the inability to read the full inscription or determine the issuing entity.
