Gold-plated connectors

Check the female side with a bright light — gold visible down the full contact length, on both mating halves, over a non-magnetic base. Then confirm with a magnet. Telecom DIN 41612 and mil circular connectors are the top of this category.

How to spot it

Card-edge sockets, DIN 41612 backplane connectors with dozens to hundreds of gold pins, D-sub, SCSI, mil circular, header strips.

At 4 Aug 2026 spot prices that works out to $78.3 per pound of contained metal — Gold 0.6 g = $78.3. A refiner paying $3.1 returns about 4% of that, which is normal: refining costs money and the buyer takes a margin.

Safe removal

Working temperature: Heat gun 400–500 °C

Heat gun 400–500 °C or hot plate 250–290 °C, then pull the whole connector off with pliers. Most refiners prefer them intact — de-pinning only pays if you have a shear and real volume.

Hazards

☠ Lead — dust more than fume

NEVER dry sweep or use compressed air on a scrapping bench. HEPA-vac or wet-wipe only.

☣ Beryllium copper

NEVER put BeCu in a grinder, a sandblaster, or a melt.

The common trap

Only 15–30 µin hard-gold mil-spec contacts reach the top of the range. Commercial 'gold flash' is 2–3 µin — ten times less. Gold-coloured bare brass is extremely common.
