Actually, the steel won't rust unless the coins are exposed to humidity or
contaminants (finger oils). HOWEVER, the zinc plating on these coins is
highly reactive and reacts with just about anything. Getting that bright
silver color to remain unimpaired approaches impossible. I wonder is
intercept-shield has been tested for protecting zinc?
Whatever you do, handle the coins with clean, fresh cotton jeweler's gloves
or clean plastic tongs (like stamp collectors use) only (or avoid handling
them at all). A coin tube is probably about as good as you will get for
reasonable cost bulk storage. Some older tubes shrink as they age, and
these should be avoided since the coins can be nearly impossible to remove
and who knows what got deposited on the coins (I'm not sure of the material
used in these tubes). I would put the tube(s) in a archival quality bag and
drop some silica gel packets into the bag in order to reduce humidity.
In another 50 years bright silver, unspotted steel cents will probably be as
rare as original bright red unspotted large cents.
