Try a search for "holders" in this newsgroup. We've had some terrific
threads about this very topic.
IMO, you can't go wrong with Air-Tite, Eagle, Whitman (plastic), or
Kointain holders. Capitol Plastic has a huge line of holders but, for
me, thay aren't as good a solution for a decent sized collection.
Each holder has its advantages and disadvantages and no one holder is
universally the best for all people and all situations. You'll have
to get information on all of them, and then decide how you wish to
store and display your collection.
IMO, Air-Tites are the best long-term solution. They have a huge
assortment of holders, display cards, albums, and presentation cases.
They are expensive though. These are the holders I use for all my
Standard cardboard and mylar 2x2 holders are very inexpensive and you
can easily store and display a huge number of coins. But IMO they are
not suitable for very long term storage or for valuable coins.
Several members of this newsgroup use them very successfully though
and recommend them. For circulated or inexpensive coins, they are a
terrific to display and store your coins. I use them for my Mardi
Gras doubloons, circulated world coins, and transportation tokens.
Whitman two-piece holders are pretty airtight, inexpensive, and allow
you to display your coins in 20-pocket pages (get mylar pages!) in
standard three-ring binders. Though I suggest using a nice cloth
bound archival binder, it looks a LOT better than a standard vinyl
binder. An inexpensive solution that can easily expand to display
lots of coins. You may have to use pages that have slightly looser
pockets to fit the Whitman holder.
The Eagle holders are terrific too. Similar to the Whitmans (but in
three-pieces with a flexible mylar window), they are available in
white and black. Personally, I think an album of black Eagle holders
would look great! A little more expensive but they look better than
Kointains are terrific for protecting coins but are only available in
6 (7?) sizes which is a problem for non-US or early-US coins. I would
recommend them for use as part of another holder, e.g. place the coins
in Kointain holders then into cardboard 2x2's. This would give more
physical and environmental protection than 2x2's alone, but won't cost
a lot. They have a definite place, I just haven't figured out where
they can fit into my collection.
