What if they are 'gold plated' contacts-- does this change the scenario at
all?
On another note-- how does one tell the checmical makeup visually between
bronze, gold, etc.?

served to help keep them clean. Modern very low voltage/low current keying
circuits don't do that and the contacts easily become intermittent as they
collect a coat of oxides and dirt. Such contacts need no such delicate care
as perhaps modern contacts might, although it'd be foolish damage them
further needlessly. (Some old keys do have silver contacts which should be
treated with care, especially if they're plated and not solid silver. Silver
oxide is a good conductor, so even if they appear black they are still good
electrical contacts. If they become intermittent it's not because they are
oxidized but because they are actually dirty with a film covering the
silver. Very gentle wiping should restore good contact.)
