I used a cyanide peroxide bombing solution to strip gold and silver off plated parts. The values were simply recovered using zinc. This technique requires good ventilation and caution because it can boil over violently if you are not careful. But once you are used to it and know what to look for it can be used effectively. Again the solution was to remove the plating and preserve the base material so it could be re-plated, so these pins would produce a silver cyanide solution with very little effect on the underplate or base metal.
