[Amps] Silver Plating Tank Coil ??

[ToddRoberts2001 at aol.com]

Hi All,
If the main goal is to prevent tarnish on a tank coil and
keep it looking nice, 
wouldn't gold plating be the best to use? Even silver will
become blackened  with tarnish after a few years
out in the open atmosphere. I doubt much if any 
difference in efficiency could be measured with a gold plated
coil vs. silver plated, at Ham power levels at least. Gold
plating might be superior also for a roller-coil to keep the
moving contact tarnish-free?
 
As I understand it gold plating is not really all that
expensive on small items compared to silver plating,
if you have it done by someone that specializes in plating.
I read that people have all kinds of things gold 
plated, from car keys to doorknobs!
