Although I have heard of at least one horror story where the plastic
envelopes melted and bonded to the coins in a house fire, storing
coins in an archivally-safe plastic seems to have many advantages.
Corrosion Intercept is now available in polyethylene film bags,
molded slide holders, and lined acid-free boxes designed for storing
coins. (Corrosion Intercept traps corrosive gases in the copper
molecules bonded to the plastic polymers.) The manufacturer informs
me that he will soon be stocking:

    *   Bags - Zipper and Flat
    *   Boxes - individual slab boxes and box which will hold 10 of
        the smaller boxes
    *   Envelopes to hold 2" x 6" coin slides
    *   2" x 6" cores and plastic slides
    *   2" x 2" plastic snap and Intercept core

More information on Corrosion Intercept, and links to the
manufacturer's site may be found on our web site at:
