Gold-Plated Industrial D-Subminiature (DB9) Male Connector
Electronic Component (Industrial Connector) · Yellow Gold plating over a base metal alloy (typically steel, brass, or phosphor bronze).
Purity: Flash Plating (approx. 0.0001% - 0.01% gold content). Specifically, the pins are likely plated with 10-30 micro-inches of 24K gold over nickel/copper. This is not solid gold.
Type
Electronic Component (Industrial Connector)
Purity
Flash Plating (approx. 0.0001% - 0.01% gold content). Specifically, the pins are likely plated with 10-30 micro-inches of 24K gold over nickel/copper. This is not solid gold.
Gold Type
Yellow Gold plating over a base metal alloy (typically steel, brass, or phosphor bronze).
Weight
Total weight approx. 10-15 grams. The actual gold content is negligible, likely less than 0.005 grams.
Description
This is a salvaged industrial D-Sub male connector, commonly used for serial communication in computers and heavy machinery. While it displays a gold color, this is purely functional plating designed to prevent corrosion of the electrical contacts. It is an industrial scrap item rather than jewelry or bullion.
Key Features
Functional gold-plated pins for conductivity; D-shaped metal shield for EMI protection; dual mounting flanges.
Color & Finish
Yellow-gold hue with a dull, industrial matte finish. Significant surface oxidation, pitting, and dark spotting (non-gold corrosion) are visible.
Hallmarks & Stamps
No metallurgical hallmarks (e.g., 14K, 585) present. May contain manufacturer part numbers or logo stamps on the metal housing, which are typical for IT components.
Dimensions Estimate
Standard DB9 footprint: approximately 31mm width x 12.5mm height housing.
Gemstones & Inlays
None. The 'studs' inside are electrical contact pins made of gold-plated copper alloy.
Clasp & Closure
Two screw-mount holes for chassis attachment; friction-fit pins for electrical mating.
Chain & Links
Not applicable. Rigid industrial housing with fixed internal pins.
Craftsmanship Details
Mass-produced via industrial stamping and electroplating processes. Soldering points would be visible on the reverse side (not shown).
Authentication Indicators
Red flags for solid gold: Presence of rust/oxidation spots (gold does not rust); sharp industrial edges; lack of purity stamps; weight-to-volume ratio inconsistent with gold.
Origin & Maker
Unknown industrial electronics manufacturer (e.g., Amphenol, TE Connectivity). Likely manufactured in East Asia or North America.
Era & Period
Modern Computing / Industrial Era (Late 20th Century to Present). This specific style was standard for RS-232 serial ports in the 1980s and 90s.
Age Estimate
Likely manufactured between 1985 and 2005 based on the patina and connector type.
Cultural Significance
Represents the 'Digital Gold Rush' of the late 20th century where precious metals became vital components of the global communication infrastructure.
Condition Notes
Poor / Scrap Grade. Surface shows significant corrosion, dirt, and mechanical wear. Plating is worn through in several areas, revealing the base metal beneath.
Value Estimate
Intrinsic 'melt' value is near zero ($0.01 - $0.05). Market value is based on weight as 'e-waste' or 'gold-bearing scrap,' often valued at a few dollars per pound.
Care & Maintenance
Not intended for jewelry care. For functional restoration, use contact cleaner or isopropyl alcohol. Not suitable for polishing or jewelry immersion.
Similar Items
VGA connectors, HDMI internal pins, and gold-plated CPU pins (though CPUs generally have much higher gold density than D-Sub connectors).
Interesting Facts
Gold is used in electronics because it is a superior conductor that does not tarnish like silver or copper, ensuring a reliable connection for high-speed data or low-voltage signals.
