How do silver and gold bullion coins come packaged?

I’m thinking about buying some silver bullion coins for investments (go along with savings and mutual funds) and generally just for the idea of having some coins that would have some worth to them either now or in the future. I want to buy gold bullion coins as well but I’m going to wait out that to see how the US economy continues and if the price of gold is going to drop or not. Not in any rush, in my early 20s. Also silver fits more into my budget after I take care other other things, student loans, and put away money in savings.

I’ve been looking at Kitco.com as a place to buy from but I’m wondering in general how are silver and gold bullion coins packaged when you buy them?

Are they simply sent in packaging and you can touch them with your hand or are they perhaps encased in plastic that you might be able to open if you want? Or is that something you have to buy yourself? Here is an example of what I’m referring to.
