Gold Type
Yellow Gold plating; an industrial-grade electroplating meant for conductivity rather than jewelry aesthetics.
Weight
Estimated total weight: 2-3 grams. Gold content: Negligible (less than 0.001 grams).
Description
This is a broken 3.5mm stereo audio connector, commonly known as a headphone jack. It features thin gold plating over a base metal alloy. The plating is utilized for its anti-corrosive properties and electrical conductivity rather than intrinsic metal value. The piece has been severed from its original wiring, leaving exposed solder and internal wiring remnants at the base.
Key Features
3-pole (TRS) configuration, gold-plated surface for oxidation resistance, and universal compatibility with standard audio ports.
Color & Finish
Vivid rich yellow gold color with a high-luster, industrial polished finish. The surface is smooth for low-friction insertion into ports.
Hallmarks & Stamps
None. Industrial electronic components rarely feature purity stamps as they are not precious metal items.
Dimensions Estimate
3.5mm diameter (standard mini-jack), approximately 14-16mm in length for the plug portion.
Gemstones & Inlays
None. Features black plastic/polymer insulating rings to separate the tip, ring, and sleeve connectors.
Clasp & Closure
Friction-fit connector. The base shows broken solder joints where it was once attached to a cable.
Chain & Links
Not applicable. The item features a cylindrical shaft with a tapered tip for mechanical alignment.
Craftsmanship Details
Machine-lathed base metal with industrial electroplating and injection-molded plastic insulators. Designed for functionality and mass-production efficiency.
Authentication Indicators
The 'gold' is a surface finish only. Red flags for solid gold include the industrial application, the presence of insulating plastic rings, and the visible silver/brazen color where the solder attaches at the top.
Origin & Maker
Mass-produced industrial component; likely of East Asian origin (China, Taiwan, or Vietnam). Manufacturer unknown.
Era & Period
Contemporary (Late 20th century to present). This specific design became the global standard for consumer electronics in the 1980s.
Age Estimate
Produced within the last 15-20 years based on the standard TRS configuration and commonality of gold-plating in consumer tech.
Cultural Significance
Represents the digital audio revolution and the era of portable personal electronics (Walkmans, iPods, and smartphones) prior to the transition to wireless Bluetooth technology.
Condition Notes
Poor. This is a scrap component. The metal is mechanically sound, but it has been ripped from its housing, showing jagged solder points and wire fragments at the terminal end.
Value Estimate
Market value: $0.00. Melt value: Virtually zero. The cost of refining the gold from a single jack exceeds the value of the gold recovered.
Care & Maintenance
Clean with isopropyl alcohol to remove oils and dust from the contact points. Avoid abrasive cleaners that can strip the micron-thin gold plating.

Interesting Facts
Gold is used in electronics because it does not tarnish or oxide like copper or silver, ensuring a 'clean' audio signal over many years of use. However, the amount of gold is so small that it is often referred to as 'gold flash' plating.
