My plants love humidity, my coins don't...

Maryland has a climate the changes from humid in summer to dry in winter.
Keeping my plants happy is no problem during the summer but I have to try
to keep my coins dry. Of course, slabbed coins aren't effected.
In winter, I have to add humidity to the air to keep my plants healthy.
In essence, I keep two climates in my house.
My most valuable coins are in a safe with a bag of silica gel.
Many, unfortunately are exposed to the moisture that will, I fear, eventually
take it's toll on the copper and silver coins.
Anyone else have this dilema ? What have you come up with to deal with it ?
Thanks.

Yeah I live on the Gulf Coast near the beach where there is always warm moist salty tropical air blowing. I run my HVAC year round and it keeps my house climatized. As long as the leather on my gunslings & cases isn't mildewing and the metal isn't rusting my coins are doing fine.

I am curious...

Coins in PCGS holders are not a problem right?

I try to keep my coins in a safe or safe deposit box...but from time to time I bring them out Humid or not.

Is this a problem if they are in holders?

Thanks

Silica gel is great. I live in Florida, where it is constantly humid and I keep my PCGS slabs in the blue boxes in safe deposit boxes. So far so good. I would also endorse Intercept shield products, I just wish they made one that could encompass an entire PCGS box.

I try to keep most of my coins protected by silica gel. The ones not in my safe, are in dry boxes with silica pacs. These dry boxes are made for storing photography equipment, but work well for mint sets, proof sets, etc.

I store my less valuable coins in a big clean popcorn can with a fresh pack of silica gel. Works well.

Its simple. Ship your coins to me in the summer. In Oregon we are wet in the winter and dry all summer.

Josh, coins in most reputable grading service holders are immune to
humidity and pollutants.
Coins not in holders are suseptible to damage from contact with any
environmental contaminants.
Short exposure to humidity shouldn't pose any real problem, so feel
free to look at your coins any time. Just watch for any changes over time.

By the way, silica gel will eventually become saturated and lose it's water-
absorbing abilities.
It can be dried in a 300 degree oven for three hours and used again.
Just be sure the packaging isn't damaged by the heat.

Where did you hear this? They aren't water-tight, so how can they be immune to humidity and pollutants?
