As already noted many companies jumped on the band wagon making folders, boards, holders, books, etc., for the
State Quarters and didn't care to look into proper materials. Also, many are as noted just open to the air. Some have glued backs in the slots due to the manufacturing process. The backing sheets are glued continuously and the slotted page layed out on it. Therefore the slots have glue on the back for coins to come in contact with. Pressing coins into those slots with a thumb or finger will leave a coating of oils and acids from your body on the coins. In the near future many of these cheap type collector items for those quarters will distroy the coins completely. The manufacturers of such items don't care, don't know, don't worry about tomorrow as long as people buy them, they'll make money. If in fact the edges are becoming discolored it is probably due to contact with the glue, poor quality cardboard and/or paper used to make the holder of the coins. If you are truly concerned in keeping the coins in Mint condition, I would suggest you purchase a Dansco, Whitman, Littleton type of Album where the coins are in a well made, high quality material, plastic covers on both sides. If your coins are in any type of push in holder you or someone else has already pressed a good deal of oils and acids from your thumb onto the face of the coins.
