In searching for the current and historic price of gold, the kinds of sites I'm finding seem a bit questionable. What is a reputable site for information about current and historic prices for gold?
When is a good time to invest in gold? What are situations likely to trigger a drop in gold prices? What are alternatives to gold?
Can gold prices vary between two places or countries at the same point in time ? Here is an answer but I am looking for a more detailed answer.
