Things that glimmers like gold in phones and computers and wires, are gold plated. It's likely worth the time to pluck out the shiniest parts and save them in a pile. A pile that grows in value over time. And increases in value the larger it gets.

Also, it's fun to take things apart.

Gold plating uses incredibly small amounts of gold. You would have to have a huge pile, and spend a huge amount of time creating that pile, to come up with any noticeable value. Unless you're doing it automated, on an industrial scale, I very much doubt you can even get within an order of magnitude of minimum wage.

I remember a few years ago seeing a book of gold leaf on sale at an art store. Normally it was something like $80, but on sale, it was $30. I was wondering how they could be making money on that. I did the research and found out that a typical book of gold leaf only had about $10 worth of gold in it (at the time).

Gold leaf is incredibly thin.

one of the most known italian chefs, Gualtiero Marchesi, is known for preparing gold leaf risotto, which while appearing as something only the fabled edonists of the 1% can obtain, is actually something anyone can make at home (and edible).
