It is a safe bet to say that gold will remain between $1,100 and $1,300 for the immediate future. This means that when you sell your scrap gold, the cash you earn should not be too much different one week to the next. There is no point in waiting, especially if you need money now, unless you have significant amounts of gold to sell. If you have over an ounce, then analyzing the price changes will benefit you. But most people only sell scrap gold a few grams at a time.
