jcook54 Pillar of the Community United States 533 Posts	Posted 01/15/2007 09:47 am I was wondering if anyone knows anything about "safe" humidity levels for coin storage. In my floor safe I use dessicant, but for general storage, what might be a safe level of humidity? I ask because given the winter months, I have a humidifier an can control my home's humidity levels. Any opinions? I have not noticed any damage, but am just curious. Report this Post to the Staff

However if you do know your room is very humid, perhaps you should get another larger container or a smaller container to repack the coins into less humid enviroment.

I may be 100% wrong in this thinking but it just seems to make sence to me anyhow Report this Post to the Staff
Learjet Pillar of the Community Australia 655 Posts	Posted 01/15/2007 1:45 pm I know, it doesn't make sense to me either but here's the story. http://allgoldcoins.co.uk/allgold/i...ro_story.htm I have read that gold is impervious to attack from many substances but I thought the ocean currents, as you say, would wear at them. The couple of 130+ year old gold sovereigns that I have do seem to still look great. And they don't tone like silver or copper. It's one of the reasons I've turned to them after getting disgruntled with the whole toning business of other coins. Report this Post to the Staff
