I recently went to my basement and yanked a old security system off my wall, it was installed in 1979 when I had first purchased my home. I went to break down box looking for valuable caps and capacitors, or any gold chips that may lace the boards. Sadly I didn't find much.
What I did find was about 10 - 15 relays, each had little gold squares or silvery buttons. I broke off all the contacts and dropped them on my scale, there is only a small amount each contact about the size of a pin head or two.
in total there is about 15 gold "Colored" contacts, and 12 or so "Silver Colored contacts"
The mass collectively weighs in at about 7.5 grams.
ill post pictures as soon as I can get my hands on a respectable Camera, that isn't cradled in about 10 pounds of submersible housing.
