Depends on how long you want to store them. Any kind of plastic will
rot
eventually. Some kinds faster than others. They sure won't make plastic
food
bags anywhere near what you would want for keeping things fresh. They
make
them for keeping food fresh for a short time--months not years and
years.
You could always replace them every other month to be sure--sounds like
a
pain to do. 2x2 mylar flips is the best long term but you still should
change those every couple of years. There really is no sure fire way to
keep
the ravages of time from eating away at a coin

So this is the gist of what I take from this discussion of the
progressivity of toning that has been continuing for the past couple of
weeks.

Any contact with oxygen will make the toning progress from golden to
black over time. The only suggestion for removing oxygen is to use a
food saver vacuum device, but that involves collateral damage that is
almost as bad.

So once you have allowed your coins to tone, there is no safe way to
arrest the chemical reaction? No way to achieve the desired level of
"doctoring" and then freeze it?

Most all coins have a set way that they usually will tone out. This only
occurs over time and when you try to speed up the process the coin will end
up not looking naturally toned. Once they get aged fast by unatural means
they will also degrade unnaturally fast. A heavily doctored coin will
continue it's rapid degradation no matter if you froze it in liquid nitrogen
just like they did with Ted Williams.
