Actually I work with electronics just about daily, and I can tell you lots of connectors get gold plating for corrosion resistance that doesn’t effect continuity. But yes in a post apocalypse setting I’m sure it wouldn’t be of much value… In the apocalypse I suspect if any metal holds a high value it would be copper for its usefulness in making tools and electronics. Making bronze tools and weapons is easier than steel so I suspect it would be in very high demand. Hopefully we never have to find out!
