Clarification. I am not looking for a source to buy gold. I have been buying gold for 40 years and know how to find reliable sources.
As I wrote in my original post, I am trying to help someone who knows nothing about gold to know if a given source is reliable or not. She has had several replies from people recommending places on the forum where she posted. All of them (in my opinion) are not reliable. I don't want to be one more person recommending particular places--I could easily be just another scammer channeling her to my shady business. Rather, I want something like a list of reliable sources from some sort of objective organization such as a government office, or something that the man on the street can trust as reliable.
