Just the fax, Maam...

Exactly. It does have better corrosion properties, which is the
ONLY argument for using it. The RCA connector design is such that a
good drag scrape occurs on the center pin with each insertion. So any
good metal works even after some minor oxidation.

Heheheh... I have a GRIP on reality, I do not think I have any
GRIPES with reality. I have always known the tiers of metal
conductivities. Strange, I even knew it as a kid.

Silver plate is best. In fact, aside from silver being the best pure
element for electrical conduction, its oxide, in pure form is so far
the best conductor of all.
Nickel cadmium was the de facto plating for decades, but California
and others claimed that cadmium is a bad thing. It is, in pure form
and in many compounds.
Funny that since the compound/alloy mentioned (platings) doesn't
pose a cadmium safety/health issue.
