1oz of gold for every 100oz of silver. You can buy paper PMs also but when the stock market crashes that will likely crash too before mooning after, so don't sell them like a retard. For physical just find the cheapest rounds you can with the smallest premiums.

If the coins are Dollars they'll command a good premium. 5 cent coins do as well. I don't think Canadian Junk commands much of a premium right now, you could probably get a premium if you sold on Ebay, but you'd have to know what you're doing.
