Description
This is a utilitarian vintage door knob crafted from cast brass. While its color mimics the appearance of a 10K or 14K gold item, it is a piece of residential hardware. The surface shows decades of handling, resulting in a unique patina and 'verdigris' development that distinguishes it from precious metals.
Key Features
Concentric circle design on the face; spherical body tapering to a neck; heavy oxidation and surface pitting characteristic of base copper alloys.
Color & Finish
Oxidized dull yellow with significant aged patina, surface pitting, and dark tarnish spots. The finish is worn, showing a matte, non-reflective surface typical of weathered base metals.
Hallmarks & Stamps
None visible in the primary view. Commercial hardware typically features internal casting marks or small manufacturer logos on the underside of the rose or spindle, rather than gold purity hallmarks.
Dimensions Estimate
Standard 2 to 2.25 inch diameter knob with a 2 to 3 inch projection.
Gemstones & Inlays
None. The item is a monolithic metal casting.
Clasp & Closure
Not applicable. This is a mechanical hardware fixture designed for a spindle and latch set.
Chain & Links
Not applicable. Functional rounded knob profile.
Craftsmanship Details
Industrial sand-casting or die-casting. The finish was likely a clear lacquer originally that has since worn off, allowing the underlying alloy to oxidize.
Authentication Indicators
Red Flags for Gold: The surface exhibits 'brassing' or oxidation spots that do not occur on high-karat gold. Gold does not pit or tarnish with black/green spots in this manner. The luster is dull and metallic rather than vitreous or buttery like solid gold.
Origin & Maker
Likely American or European industrial manufacture (e.g., Baldwin, Schlage, or Yale).
Era & Period
Early to Mid-20th Century / Colonial Revival. The orb-shaped design is a staple of mid-century residential hardware.
Age Estimate
Circa 1940-1970 based on the wear patterns, casting style, and specific oxidation colors.
Cultural Significance
A representation of mid-century domestic architecture and industrial design, symbolizing the 'American Dream' housing boom where brass fixtures were preferred over cheaper steel for their longevity.
Condition Notes
Fair. Significant surface oxidation, pitting, and fine scratches. The structural integrity appears sound but the aesthetic finish is heavily aged.
Value Estimate
$10 - $30 USD (Antique/Salvage value). The value is based on its utility and vintage aesthetic, not metal content. Melt value is negligible (based on scrap copper/zinc prices).
Care & Maintenance
If restoration is desired, use a brass cleaner (e.g., Brasso) and a soft microfiber cloth. To maintain the vintage look, simply wipe with a damp cloth. Do not use gold polishing cloths as they are too soft for this heavy oxidation.

Interesting Facts
