"hard gold edge fingers", which is gold over a layer of nickel, required to prevent the gold aroms from dispersing through the copper.

If you just say "gold edge fingers", you'll get "gold flash", an ultra-thin layer of gold without nickel, which will wear off after only a few mating cycles. Due to the previously mentioned dispersal, it can still _look_ gold after that, while not actually providing the corrosion resistance of hard gold.
