<p>[QUOTE="desertgem, post: 2482455, member: 15199"]Some of the old ( 20 yrs or so) ones had some pvc windows, but they tore too easily and they were replace by the mylar types of plastic, so I don't suspect that from modern 2x2 as much as staple holes. They penetrate from the outside through the mylar and environmental gases and moisture have access to your coins, but it is the same as all coin holders, storage beyond the holder must also be considered.</p><p>Also stainless steel staples should be used in the 2X2, as regular steel staples reacts rather quickly if moisture is high.[/QUOTE]</p><p><br /></p>
