Vintage acorn shape metal coasters, PAT. PEND., with the factory-molded two-indent design shown in the photos. The form and finish suggest a decorative table accessory, exact maker and country of origin not identifiable from the images.

• Acorn-shaped coaster design with two indentations and a hooked tab detail at the top.
• Metal construction with a molded, raised leaf/vein motif in the center.
• Marked PAT. PEND. on the underside/inner surface as shown.
• Factory-molded construction rather than hand-formed work.
• Four coasters are shown in the photos; set size is not otherwise determinable.
• Surface wear includes scratches, scuffs, tarnish, spotting, and residue consistent with use.

Made for protecting tabletops from drink rings, these would also display well as a small vintage metal collectible or desk/tabletop accent today.
