<p>[QUOTE=&quot;desertgem, post: 2263728, member: 15199&quot;]Considering the glued vs. stapled, the Stapled are superior IMO, if:</p><p><br /></p><p>You use stainless steel staples, and a stapler that flattens the ends flat against the cardboard and not in a loop to avoid damaging adjoining coins. And a tight seal is essential to prevent environmental damage.</p><p><br /></p><p>Why not glue? Less and less of such cheaper mounts are made in countries that do not publish MSDS so you can&#039;t see if the adhesive can outgas chemicals that might cause damage. Also in my hot area ( desert) I have seen some of the glued ones lose the strength to hold properly after several years, especially large coins.</p><p><br /></p><p>Here is a photo of 3 coins that over 20+ years developed toning in the area where &quot;steel, not stainless&quot; staples eventually corroded a little, and since they pierced the inner mylar area, the corrosion/toning eventually spread to the coin.</p><p><br /></p><p><img src="http://i455.photobucket.com/albums/qq279/desertgem/stapletoning.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" />[/QUOTE]</p><p><br /></p>
