I would also recommend a dehumidifier. Not sure that's a good investment in Wyoming. |

To CCF! Quote: with Dave. My sister recently moved, and noticed her home had a lot of humidity. She didn't want dehumidifiers, so she got those bags you can hang that pull in moisture. I don't know what they are called, but she said they work well. Worst case scenario, get a new Dansco, etc (but I know they are expensive). Is this what you mean thisistheshow? https://www.amazon.com/DampRid-Hang...difiers+bagsErrers and Varietys.

I use a dehumidifier all the time. I use mostly Whitman Albums and have never had a problem of any kind. |

Dehumidifier - good investment in your coins. Also remember, MORE LAYERS = MORE BETTER! Your desiccant packs should be in the same bag as your coins, then another outer bag to protect your desiccant along with a sacrificial copper cent and maybe a junk silver coin. Leave them open and loose in the bag to absorb any bad stuff that makes its way in. |

Lol. I like meat!!
I'm hoping to not run into the same kinds of problems that the open books have. I'm sure that aside from moisture, air is a problem. My coins are now stored in 2x2 limiting air, tucked into plastic slips further reducing air flow and then in a binder that slides into its own sleeve. I store that in a wooden drawer with some small silica packets. My hope is that wood and packets will soak up any extra moisture that's in the air and the way the coins are stored reduces the amount of air flow to the coins thus limiting the amount of toning that will occur. I also don't have AC in my home so I don't have any issue with adding more moisture to the air. Oh, and I don't have AC not by choice. Man it gets hot lol.

I used to live in the humid south, and now live in dry Wyoming. Again ... due the combination of elevation, temperature and relative humidity, the moisture in the air in Wyoming is far less than in many other parts of the country. This already gives you a head start on moisture issues, and means a dehumidifier is unlikely to be a good choice to further reduce moisture in the air where you live (you will pay to buy it, pay to run it, and it will not remove much moisture from the air). The dessicant approach shown by others is likely to be the most effective. |

I'd avoid albums if you don't want your coins to tone. All albums have paper chemicals in them, some of the older ones have sulfur to avoid bugs eating the paper. This turns coins black in a few years.

Over thirty years in Dansco albums, no issues. Keeping in mind that mine are lower value or common modern coins.
Higher value high grade coins I would probably defer to Andrew's opinion.

Be careful using those moisture absorbing packs. Many people use them and forget about them. After a while they are full of moisture and can actually leak moisture into an area. People tend to not understand they have a limit of absorbing. Once full, become either useless or dangerous. I never have used them and live in a high humidity area. I put most coins in Albums and then in Zip lock bags with as much air pushed out as possible. I use mostly Whitman Albums but also any other brands as long as they are cheap. So many people say they use Dansco because they look expensive then hide them away anyway. I keep most of my Albums in safe deposit boxes but for the coins at home, I use a dehumidifier. In well over 60 years, no problems.

I need to check on the packs I have as some of them are not rechargeable and will need to be thrown out. Thanks for the head up Carl. |

The key to Dansco albums is to buy the slipcovers... This is from them...
"Dansco Slipcases or Slipcovers are used to limit air movement around your coins. Your Dansco albums slide into these so that the binder's spine is still exposed so you can read the album's gold leaf title and album number. The Dansco Archival Quality Slipcases are produced with Silver-Guard Corrosion-Inhibiting protection. No other product on the market matches Silver-Guard Corrosion-Inhabiting protection. This Military Specification material permanently neutralizes corrosive gases in the air that can cause toning and discoloration. This works with silver, gold copper, and nickel coins and metals, medallions, bars, and ferrous metals. Dansco Coin Albums have always been made with the best archival materials and with the addition of the finely crafted slipcase the protection is invaluable".

I guess it's not a chemical bond? That's right. It's adsorption. Something like when a sponge soaks up water. As justcarl points out, once the silica gel is saturated, it can't absorb any more moisture, and indeed, it will be likely to release moisture if the temperature decreases, or the relative humidity decreases. In air conditioned places, this is not much of a risk, but if you drove your collection from Missisippi to Wyoming with saturated silica packs, they would definitely release moisture on the trip (so would a saturated sponge). |
