Metalwork / Hardware

Uncommon

Identified on October 2, 2026

Estimated Value

$20-$150

The object appears to be a small square or rectangular copper-alloy metal fitting with a raised central boss or rivet-like projection. The surface is extensively corroded and encrusted, making precise identification difficult. The form suggests it may have been a decorative mount, furniture fitting, harness element, strap end, or architectural hardware. The visible raised circular center and surrounding flat plate are consistent with a functional attachment piece rather than a standalone decorative object. No maker's mark, inscription, or clear ornamentation is visible due to corrosion.
