Read K8RI's response again. Silver is the best conductor listed and I have
many silver plated Andrew and Amphenol connectors. Actually aluminum is only
slightly worse than gold as a conductor so why would anyone use gold ground
wire? As Roger stated silver does oxidize, this reduces it's conductivity.
I make sure that my connectors are clean before using them.

I am not certain how those numbers apply to conduction of current, but it
seems obvious they differ from what is used by industry. I have never seen
copper plated PL259's. Same for pins used in commercial plugs/sockets.

Ahhh...Gold is not the best conductor compared to Silver
*Gold*: 2.24: Copper: 1.724: *Silver*: 1.59:
So both copper and silver are better conductors than gold with silver being
almost twice as good as gold. Gold OTOH is tarnish resistant and is almost
like a lubricant on contacts
Silver easily corrodes and copper is not far behind.
