Do not buy anything with PVC (aka vinyl). People often suggest 2x2 cardboard holders and those are nice and cheap ways to store coins but just make sure they are PVC free or "inert". Mylar is a brand name for this type of plastic.
Next is boxes for storage. I am looking into Intercept Shield Boxes which are coated on the inside with an anti-corrosion agent (I believe its made out of copper, so the air reacts with it instead of your coins, like a sponge for corrosion). I'm not sure if it's necessary but I'm doing it to protect a few high grade coins I started my collection with. Also don't store coins in wooden boxes and make sure humidity doesn't get high near your coins.
Also about buying bulk... keep in mind that rarely is any lot of coins unsearched. I'm sure the guy that's selling them likes money and has already searched the coins for valuables (barring mint errors that he didn't notice). If you want more info on hunting for coins and all you could go here: http://www.coincommunity.com/forum/...FORUM_ID=147 ... that's a subforum on roll hunting.
And of course never clean the coins.
