Safe coin holders
Mylar (non-vinyl) coins flips:
you can easily see coins, these
are inert,
however the plastic cracks with frequent use or with big
thick coins -- thus replacements are handy
This is a mylar flip
coin envelopes
must use an inner liner: polyproplyene or mylar baggies
cannot see coins but can easily label the envelopes
Air-Tite coin containers
These supposedly seal the coins in an airtight
capsule
they can also be combined with albulms/display cases where
you would not want the actual coin exposed: e.g. for a display of high
grade coins for example.
their bulk makes them a little difficult to store, and they cost more
than flips. All of these supplies can be located here

Storage
some cheap wooden boxes may not be safe
these cheap boxes seem to
release a gas which stains the polypropylene baggies brown: thus I won't
use them for coins

comparison.
The 40g silica gel canister driers cost me $3.
each.
Hopefully they last longer than the small free ones (which
don't last long at all)? At least they come with regeneration instructions
(300F for 3 hrs, although they turn blue at 250F for 1/2 hr)
Here
is a humorous site which discusses the gels http://users.adelphia.net/~jthm/
Buy the canisters and don't fool with the little ones as they die almost immediately. All of these need regeneration as they're pink. There is also a 1 kg box which is not much more expensive.
