<p>[QUOTE=&quot;MrSpud, post: 106172, member: 4621&quot;]I prefer rolls to bags of coins, but just because I worry thats the coins will get all banged up against each other more.</p><p><br /></p><p>I had a friend who stored several proof sets and Dansco Albums with coins in a fireproof safe. The coins in the proof sets ended up being covered with corrosion spots, not just toning, but black spots all over the coins. The same with the coins in the Dansco Album, many became covered with corrosion spots and a few just became toned. This was from moisture. Some Fireproof safes tend to have a high amount of moisture in them. Same with some Bank Safety Deposit Boxes. Many have high humidity to help keep paper documents from drying out and becoming brittle. Not good for coins. I lived in Florida for several years and my copper coins in albums all turned from red to brown. I have a relative who lives on the Gulf of Mexico who has a lot of nice coins, but they are all basically hazing over. It all depends on what the climate is where you live whether or not dessicants are needed. </p><p><br /></p><p>Wood and paper products can outgas acetic acid and sulfide chemicals, moreso when humidity rises above 40% RH. Changes in temperature can cause condensation if the temperature dips under the dew point. Unfortunately, the condensation won&#039;t be composed of pure distilled water, rather it will be mixed with whatever else is in the air and on the surface that it condenses on. Also, many non-active corrosive agents can become active if the moisture gets higher.[/QUOTE]</p><p><br /></p>
