Gold mechanical keyboard?

I found an old keyboard, decently old, 15 20 25+ years i think, i. 28 and its something ive never seen so i thi k its pretyy aged, i pop a key mechanics box thing open and bam, what i think is gold plating, amiright? If so i just hit the goldpot right? Having trouble uploading pictures but I believe it's gold plated brass spring deep yellow and if a copper piece with a yellow stripe on its a little brighter not so deep as soon as I can get a picture everything make sense it's a contact it's old why not
