Gold Fixed Income

Gold is not earning any yield in the traditional sense. It's a matter of, i hold on to it, and i have confidence that in some amount of time, it'll be worth more than it is now. But if i could take gold that i'm just sitting on anyway and earn some kind of return on it, well, that would be an unbelievable bonus for basically having to do absolutely nothing what i don't understand is whalt i have to send you my gold, or would there just be some certificate? Or would i buy the gold from you? How does it actually work? Right?
