I don't have her email handy, but she can tell you everything you would ever need or want to know about precious metals investing.
Now, for my personal opinion, I prefer to own American Eagles and generally the most recent issues as the premiums are generally lower. I also prefer 1 oz. coins over the smaller incremental ounce coins, again due to premiums. I also live in America so the Eagles are generally the most "liquid" if you were to decide to sell. Maple Leafs are also pretty popular and very cool looking coins.
I have also owned some Perth 1 oz. bars, I like them because they come packaged and numbered, you know exactly what you've got and don't have to worry about condition unless you bang up the case or something.
Kruggerands are a fine choice, but as pointed out you do need to know how much gold is actually there so you pay the right price.
The St. Gaudens are nice, I'd like to own one but just have never pulled the trigger. When you get into these and other of the older and/or turn of the century gold coins, you're starting to venture into the "numismatic" value of the coin as well, which is more akin to it's "collecting value" beyond just the gold component. That's a whole other subject on these coins, grades and conditions matter, it's pretty subjective stuff probably for more advanced "collectors". Most investors I know don't mess with those coins, but if you know what you're doing it's also a way to go.
Good luck with it!
