My L.E.'s still grade 100, even after being in a plastic page for a year, Andy. You needn't worry about lowering the grade on your chips when you finally decide to have them certified and encapsulated.

30 Pocket pages are the way to go. 50% more chips in a binder and you don't have a pile of tape or staples when you remove a chip from the page. Be sure to get the Cowan brand pages with the thicker, softer plastic. The cheap, thin ones are a real pain to deal with.
