<p>[QUOTE=&quot;bcuzz1, post: 1618417, member: 43464&quot;]Perhaps someone can explain this and what I should do. I am not sure if this is bad or not. </p><p><br /></p><p>About 8-10 years ago, I put a bunch of coins into square tube holders. They were made by Colella Productions which I think was Coin Tubes of Nevada (since out of business I believe). Last night, I was organizing and when I opened the box with about 100 rolls of dimes (mercury and roos), the tubes are turning green. The green only goes up to the height of dimes in the tubes, so I&#039;m guessing it is some reaction between the dime and the tube. Out of 100 rolls, however, a couple were not turning. The ones that did not turn contain un-circulated dimes. All of the tubes with circulated dimes have developed a green tint. Other tubes with old quarters, halves, and dollars are just fine and do not have a green tint.</p><p><br /></p><p>The dimes themselves in the green tubes seem to be fine. Also, the green has developed in the material of the tube. That is, I opened the tube and tried cleaning the inside and nothing comes off the inside wall.</p><p><br /></p><p>The pictures below. The pic with three rolls shows the green tint climbing to the height of the dimes. The pic with two rolls shows one that is turning and one with un-circulated dimes that did not turn. Last is a pic of the bottom with the company.</p><p><br /></p><p>I am trying to decide whether to replace (1) all the dime tubes, (2) just the dime tubes turning green, or (3) all the tubes, even the ones with quarters, halves, and dollars.[/QUOTE]</p><p><br /></p>
