Type
Hollowware (Tea and Coffee Service component)
Maker
International Silver Company, based in Meriden, Connecticut. Formed in 1898 from several smaller silver companies and became the largest silver manufacturer in the world.
Material
EPNS (Electroplated Nickel Silver). The item is a base metal alloy of nickel, copper, and zinc coated in a thin layer of silver.
Dimensions
Approximately 4 inches high and 5.5 inches wide across handles. Weight is substantial due to the heavy white-metal base used for plating.
Description
An ornate silver-plated sugar bowl from International Silver's popular Winthrop line. The piece features a bulbous body supported by a stepped pedestal base, dramatically encircled by a thick band of three-dimensional grapes and curling vines. It reflects the post-war American desire for traditional, 'Old World' aesthetics in household dining.
Key Features
The prominent 'Grape and Vine' raised relief border is the signature of the Winthrop pattern, making it easily identifiable even without looking at the hallmarks.
Material & Composition
EPNS (Electroplated Nickel Silver). The item is a base metal alloy of nickel, copper, and zinc coated in a thin layer of silver.
Finish & Decoration
Polished silver finish featuring a heavy applied repoussé-style border of grapes and vine leaves. This 'Grapevine' motif is a classic Victorian Revival style.
Hallmarks & Stamps
Usually marked on the underside: 'IS', 'International Silver Co.', 'Winthrop', and the number '6003'. It lacks sterling hallmarks, confirming it is silver plate.
Construction Details
Machine-pressed body with die-cast decorative borders and handles applied with silver solder. The foot is joined to the bowl with a hollow solder joint.
Functional Features
Open sugar bowl form designed for tabletop service. Includes a pedestaled foot for stability and likely once had a matching lid (or was an open cream/sugar pair).
Handle & Grip Details
Cast handles in a scroll or vine shape, soldered to the sides of the bowl. Solid cast metal ensures durability during use.
Craftsmanship Details
Industrial quality craftsmanship. The decorative border is die-cast rather than hand-chased, and the assembly is done via factory soldering. Designed for durability and visual impact.
Authentication Indicators
The 'feel' of the grape casting and the specific 6003 pattern shape match known International Silver Co. catalogs. The duller gray luster in worn areas indicates a non-precious base metal.
Origin & Manufacturing
United States, Meriden, Connecticut. Manufactured in a large-scale industrial factory setting typical of American silver production at the time.
Era & Period
Mid-20th Century (1940s-1960s) 'Victorian Revival'. This period saw a resurgence of interest in ornate, grape-heavy designs popular in the 1800s.
Age Estimate
Circa 1950. The production style and 'Winthrop' pattern cataloging suggest mid-century manufacture.
Cultural Significance
Represents the mass-market democratizing of luxury in America, where industrial techniques allowed middle-class families to own elaborate tea sets previously reserved for the wealthy.
Condition Notes
Fair to Good. Visible surface scratches and moisture droplets in the photo. There appears to be 'plate loss' (bleeding) where the copper/nickel base metal is showing through the silver on high points of the grape design.
Value Estimate
$15 - $35. As a single plated piece from a mass-produced line, value is modest and primarily decorative rather than an investment in metal.
Care & Maintenance
Clean with mild soap and water. Use a non-abrasive silver cream like Wright's. Avoid over-polishing as the thin silver layer can be completely removed, revealing the yellowish base metal.
Similar Pieces

Interesting Facts
The 'Winthrop' pattern was highly marketed as an affordable luxury for mid-century American brides, offering a prestigious 'English' look at a fraction of the cost of sterling silver.
