If it's money you can't afford to lose should something happen then maybe it's not something you should do.
If you do decide to do it, you want actual gold, not a piece of paper that says you own it. And you want to know up front what it's going to cost you to buy it from them.
We have some, not a lot and wasn't something we bought to make a quick profit on.
I would not recommend Lear Capitol. Maybe they are all the same but it was a hard pressure sell.
