<p>[QUOTE=&quot;Lev99, post: 3578214, member: 103627&quot;]I think it should be ok. I’ve not run into anything that discusses off gassing of sulfur compounds from modern cardboard. And a few of the 2x2 makers say their product is archival safe. I’ve noticed spotting on some coins due to cardboard in physical contact, so it makes me paranoid enough to keep a layer of Mylar between the coin and the cardboard. </p><p><br /></p><p>Point well taken though. You just have to keep the environment as clean as you can both on air quality and what the coins are physically touching.[/QUOTE]</p><p><br /></p>
