Numbered Aluminum or Nickel-Plated Utility Lid
Hollowware (Serving Vessel Lid) · Unidentified utilitarian manufacturer; the absence of branding suggests a commercial or industrial production origin rather than a luxury silver workshop.
Pattern: Generic banded utility pattern; likely part of a standard cafeteria, hotel, or kitchenware line with no specific collection name.
Type
Hollowware (Serving Vessel Lid)
Maker
Unidentified utilitarian manufacturer; the absence of branding suggests a commercial or industrial production origin rather than a luxury silver workshop.
Material
Likely Aluminum or Nickel-Plated Base Metal. The surface lacks the depth of sterling silver and shows scratching, oxidation, and residue consistent with non-precious metals.
Dimensions
Estimated diameter 10-15cm (4-6 inches); relatively lightweight compared to solid sterling silver or lead-weighted pieces.
Description
A circular metal lid featuring a stepped, dome-like profile designed for heat retention and protection of contents. While often mistaken for silver due to its metallic luster, the piece is a functional object likely belonging to a institutional dining environment.
Key Features
Concentric ribbing, incised '15' inventory number, and spun metal construction marks.
Material & Composition
Likely Aluminum or Nickel-Plated Base Metal. The surface lacks the depth of sterling silver and shows scratching, oxidation, and residue consistent with non-precious metals.
Finish & Decoration
Machine-brushed finish with concentric circular ribbing or banding for structural reinforcement. No hand-chasing, engraving, or repoussé decoration is present.
Hallmarks & Stamps
Incised with the numerals '1 5'. This is a size or inventory number rather than a silver purity hallmark or maker's mark.
Construction Details
Machine-spun and die-stamped from a flat sheet. The sharp concentric rings indicate automated lathe-turning or industrial pressing.
Functional Features
Includes a raised central knob for gripping and stepped ridges to ensure a snug fit on a matching bowl or base.
Handle & Grip Details
Integrated raised metal grip formed during the spinning process; no separate insulating material or attached handle.
Craftsmanship Details
Industrial grade quality; uniform wall thickness from machine spinning, with rougher finishing on the underside and number stamping.
Authentication Indicators
Negative for silver hallmarks; metal color is too grey for sterling; wear patterns suggest a base metal or aluminum rather than a precious metal alloy.
Origin & Manufacturing
Likely of North American or European industrial origin, manufactured for the food service or institutional supply industry.
Era & Period
Modern Utilitarian Period (mid-20th century to contemporary). The design emphasizes mass production over ornamental artistry.
Age Estimate
Circa 1950-1980. The wear patterns and mechanical stamping are consistent with mid-to-late 20th-century commercial kitchenware.
Cultural Significance
Represents the shift from ornate domestic silver to mass-produced, durable, and easily cleaned industrial metalware for public service.
Condition Notes
Fair condition; significant surface scratching, residual grease or organic buildup in the crevices, and loss of original luster. The 'yellowed' residue suggests use in food preparation.
Value Estimate
$2 - $10 (Nominal utility or scrap value; negligible collector value as it is not precious metal).
Care & Maintenance
Clean with warm soapy water and a degreaser. Not suitable for silver polish; if aluminum, avoid acidic cleaners which can cause pitting.
Similar Pieces
Stainless steel cloches or aluminum food warmers. Unlike silver versions by Tiffany or Gorham, these lack aesthetic value and are priced as scrap or utility items.
Interesting Facts
Numbered pieces like this were often part of larger sets in hotels or hospitals to ensure lids were returned to the correct kitchen station or matched to numbered bowls.
