Set of Three Vintage Metal Discs on Wood Surface

This set consists of three small, circular metal discs identified by their uniform round shape and metallic sheen. The discs appear to be constructed from a copper-alloy metal, likely brass or bronze, evidenced by the warm yellowish-brown metallic hue. Each piece measures approximately one inch in diameter with a thickness of about two to three millimeters. The surfaces are largely smooth and featureless, lacking any discernible struck designs, lettering, or denomination, which suggests they could be metallurgical blanks, tokens, or decorative hardware components like furniture caps or buttons. The finish shows a distinct aged patina with significant oxidation and surface wear. Small nicks, scuffs, and fine scratches are visible across the faces, consistent with long-term handling and environmental exposure. The middle disc exhibits a lighter, more iridescent surface quality, possibly due to differential tarnishing or a lingering original plating. No maker's marks, hallmarks, or serial numbers are visible. Based on the material and surface degradation, these objects likely date from the mid-20th century. The quality is utilitarian, with clean edges suggesting machine production rather than hand-forging. They are displayed against a stained wooden background with visible grain and distress marks.
