<p>[QUOTE=&quot;GDJMSP, post: 3252905, member: 112&quot;]Here&#039;s the thing with the blue Whitman folders, the older ones anyway. And I am making that distinction because I have not looked at any newer ones in about 15 years so it&#039;s possible they may be different. It&#039;s also possible they may be the same.</p><p><br /></p><p>When the folders were manufactured there is/was a thicker piece of cardboard that had the thin, outer dark blue covering glued to it. But that thin outer covering, it was completely covered in glue, the whole thing edge to edge. What this resulted in was the portion of that covering that the backside of the coin/s actually came into contact with - was also covered with glue. In other words, the coins were in direct contact with a piece of paper covered in glue, in contact with the glue itself.</p><p><br /></p><p>And sometimes, moisture, heat, pressure (from folders being stacked) and or the combination of all of these things, resulted in that glued paper sticking to the coins. This was a rather common occurrence. But it by no means happened every time.</p><p><br /></p><p>Between the cardboard, the paper, and the glue, this is why these old blue folders are infamous for destroying coins either with terminal toning or results such as the OP reported.</p><p><br /></p><p><br /></p><p><br /></p><p>Depending on the brand, it&#039;s sometimes the same thing as coin dip, or very similar to it. But products sold as commercial silver cleaners are often a good bit harsher, stronger, than some coin dips. Some of them are strong enough that even a 1 second dip will strip any and all luster from a coin. </p><p><br /></p><p>As a general rule it is strongly recommended that commercial silver cleaners not be used on coins - unless you know what you are doing and dilute it greatly.[/QUOTE]</p><p><br /></p>
