Unknown cast-metal or ceramic vessel base with maker's mark

Ceramics
Uncommon
Identified on September 20, 2026

Estimated Value

$20-$100 (higher only if identified as a documented maker or rare form)

The image shows the underside/base of a small rounded object, likely a vessel, bottle, jar, or similar utilitarian antique. The base is convex and heavily worn, with a recessed rectangular maker's mark or stamp containing what appears to be the letters 'C' and 'D' or a similar monogram. The surface texture suggests long-term use or burial/soil exposure. Because only the base is visible, the exact form cannot be determined with confidence, but it appears to be a handmade or molded utilitarian piece rather than a decorative object.

Era

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

Origin

Unknown; possibly European or North American

Material

Likely stoneware, earthenware, or cast metal with heavy surface oxidation/soil accretion

Condition

Fair to Poor; base shows heavy wear, surface encrustation, discoloration, and possible age-related abrasion. No obvious major structural break visible in this view, but the object appears heavily weathered.

Authentication

Authenticity Score

Low to Medium; the object appears genuinely old or weathered, but the exact type, maker, and period cannot be confirmed from this single image and the mark is unclear.

Provenance

Unknown. The stamped mark suggests a manufacturer or workshop, but it is not legible enough to attribute confidently. The object may have come from a household or industrial context.

Historical Significance

If authentic, this type of marked utilitarian base can be useful for identifying regional pottery or industrial production methods from the late 19th/early 20th century. The maker's mark may have research value even if the object itself is modest.
