Most pawn shops operate in the same way: you take an item into them and they give you cash for it. When you're ready you pick the item up, repay the cash and pay a fee. You'll get small prices for high-priced items, particularly gold. Good place to get money in a hurry, though, with a chance of retrieving your personal items later.
PROS: money in a hurry
CONS: your lose your items if you don't pay for the loan on time, high financing
