Where do you get the most $$$ for your 'scrap' gold?

As asked, when you have gold you don’t want, where do you get the most money: online (if so which site), at a pawn shop, at the mall’s jewelry exchange?

I have one try ounce of 10k gold in the form of two chains. I’ve had them since I was in elementary school, and if I tried to wear them now, they’d be chokers, HAH!

I’m not really desperate to make money, so I really want to find the venue that will give me the most for my money!

Thanks
