In the relatively short while that I've been collecting chips, I have found that the small plastic envelopes that you can get at hobby supply shops for about 75 cents per hundred, can be folded behind the chip. The chip can then be stored in a 20 opening page. The chip can be viewed easily, and it won't slip out.

About a month ago, I told my wife that I had an idea that would be a real winner. How about 20 pocket pages with flap closing on each opening. A week later I received some coins from a friend in Brazil. They were in exactly that type of page!
