I don't know what the need is for gold for your application but I have used shim brass as a heavy wear contact point
to mate chassis to boards.
Thin brass  sheets are available at hardware stores in various thicknesses in sheets about the size of 3x5 cards
in the window and door department. Its used behind door hinges to set the hinge in the perfect place.


 

 

Hi Again,
    So it sounds like Gold is expensive, toxic, etc.     Are there other approaches people have used if they want to make contacts (card edge fingers for example) on their boards?
