Type
Gold Key Blank / Novelty Jewelry
Purity
14K (58.5% pure gold). The remaining 41.5% consists of silver, copper, and zinc to provide the necessary hardness for a mechanical tool.
Gold Type
Yellow Gold. The alloy exhibits a warm, classic tone consistent with mid-karat jewelry standards.
Weight
8.0 - 12.0 grams. Due to the solid construction and density of 14K gold, it is significantly heavier than its brass or nickel-silver counterparts.
Description
A luxury iteration of a common household object, this 14K yellow gold key is designed as a fully functional Schlage-style house key. Combining utility with opulence, it serves as a high-end gift often presented for new homeowners or milestones. The piece features a traditional scalloped bow and a standard 5-pin length blade that can be cut by a locksmith.
Key Features
Functional Schlage SC1 keyway profile; solid 14K gold construction; 'SC' and '14K' identifying stamps; polished finish.
Color & Finish
Polished yellow gold with a high-luster finish on the bow and blade. There are visible surface abrasions and micro-scratches consistent with metal-on-metal friction.
Hallmarks & Stamps
Stamped '14K' and 'SC' on the bow. '14K' indicates purity; 'SC' likely identifies the keyway profile (Schlage C) or a specific manufacturer mark.
Dimensions Estimate
Approximately 2 inches (51mm) in length and 0.8 inches (20mm) in width at the bow. This follows the industry standard SC1 Schlage profile.
Gemstones & Inlays
None. The item is a solid gold alloy functional object with no decorative stones or enamel.
Clasp & Closure
Not applicable. The item features a standard circular key ring hole in the bow for attachment to a keychain.
Chain & Links
Not applicable. The item has a solid blade with standard residential key millings (lateral grooves).
Craftsmanship Details
Precision-milled blade to ensure locksmith compatibility; die-struck bow and hallmarking; consistent thickness across the blade to allow for accurate bitting.
Authentication Indicators
The '14K' stamp is clear and traditionally placed. The color and density are consistent with 14K gold. A red flag would be 'plating' wear on the edges, which is not visible here.
Origin & Maker
Likely manufactured in the United States or Italy. Often produced by specialty jewelry wholesalers or high-end locksmith companies that cater to luxury gift markets.
Era & Period
Contemporary/Modern. While the concept of gold keys dates back to antiquity as symbols of status, the SC1 profile specifically identifies it as a late 20th to 21st-century residential item.
Age Estimate
Circa 1990s to present. The milling design and stamping font are consistent with modern locksmithing and jewelry marking equipment.
Cultural Significance
Represents security, ownership, and the 'American Dream' of homeownership elevated to a luxury status symbol.
Condition Notes
Very Good. The blank remains 'uncut,' meaning it has not been bitted for a specific lock. Minor surface scratches are present from handling and storage.
Value Estimate
Value is primarily based on gold weight. At 10g, the melt value is approximately $400-$500 (based on a $2300/oz spot price), with a retail price for a blank ranging from $700-$1,200.
Care & Maintenance
Gold is softer than the steel pins inside a lock; if used daily, the gold bitting will wear down faster than a standard key. Clean with a soft jewelry cloth. Avoid ultrasonic cleaners if the key has been cut, as debris can lodge in the grooves.
