Electronics/Industrial Hardware - D-Sub Connector · Yellow Gold (Industrial Hard Gold Alloy). Typically alloyed with Cobalt or Nickel for wear resistance.
Purity: Gold-Plating (Flash or Micron Grade). The gold content is less than 0.1% by weight, consisting of a thin layer over base metal.

Type
Electronics/Industrial Hardware - D-Sub Connector
Purity
Gold-Plating (Flash or Micron Grade). The gold content is less than 0.1% by weight, consisting of a thin layer over base metal.
Gold Type
Yellow Gold (Industrial Hard Gold Alloy). Typically alloyed with Cobalt or Nickel for wear resistance.
Weight
5-15 grams total weight for the component; gold content is negligible (milligrams).
Description
This is a gold-plated D-subminiature connector shell and pin assembly commonly used in computing and aerospace industries. While it features a yellow gold appearance, the gold is applied via electrodeposition in a very thin layer (often 15-50 micro-inches) to ensure electrical conductivity and prevent corrosion of the base copper or steel alloy.
Key Features
D-shaped metal shield, multiple contact pins, and evidence of green cupric oxidation beneath the plating.
Color & Finish
Yellow metallic luster with visible oxidation (green verdigris). The finish is industrial electroplating over a stamped metal shell.
Hallmarks & Stamps
None. Industrial components usually feature part numbers or manufacturer logos rather than precious metal hallmarks.
Dimensions Estimate
Standard D-Sub size (approx. 30mm width); pin length approx. 10mm.
Gemstones & Inlays
None. The component features a black plastic (polymer) insulator and copper-alloy pins.
Clasp & Closure
Mechanical friction fit with screw-down mounting flanges.
Chain & Links
N/A - Industrial shell construction with pin-and-socket electrical interface.
Craftsmanship Details
Mass-produced stamped metal and injection-molded plastic with automated industrial electroplating.
Authentication Indicators
The presence of green corrosion and the physical form of an electronic connector indicate this is gold-plated base metal rather than solid gold.
Origin & Maker
Unknown industrial manufacturer (e.g., Amphenol, ITT Cannon, or TE Connectivity).
Era & Period
Late 20th Century / Modern Industrial (1970s-present).
Age Estimate
Circa 1990-2010 based on the wear and oxidation levels.
Cultural Significance
Represents the 'Information Age' and the reliance on precious metals for global telecommunications and computing infrastructure.
Condition Notes
Poor. Significant surface abrasion, heavy oxidation (verdigris), and structural damage to the housing. The plating is wearing through to the base metal.
Value Estimate
Extremely low. Value is primarily industrial scrap. The gold recovery value is likely less than $0.05 USD per unit given the thinness of the plating.
Care & Maintenance
Not applicable for jewelry standards; requires contact cleaner for functional use. For scrap, keep dry to prevent further base-metal corrosion.

Interesting Facts
Gold is used in electronics not for its value, but because it is an excellent conductor that does not tarnish as easily as silver or copper, ensuring reliable data transmission.
