Default film containers - okay for storage?


I don't know what plastic is used in film cannisters, but don't take a chance
on it. Use products specifically made and tested for coins. You'll be ahead in
the long run.

Or you could run a sample through a mass spect and see what kinda reading
you get ;-)

Probably not. Only one way to be sure. Run the "Beilstein" test.

Take a piece of copper wire and heat it in the blue flame of a gas
stove, bunsen burner or acetylene torch until it glows red. then place
the hot wire on a tiny piece of the plastic (the plastic will melt on
the copper). Place the plastic/copper melt back in the flame. If the
flame turns green or "azure", deep blue/purple, after the initial
yellow burn, the plastic has chlorine. If only yellow is seen your
flip is chlorine free and probably acceptable. Copper chloride formed
in the flame is responsible for the distinctive color.

Found a nice web page that goes over storage issues:

Is it okay for storing coins in those translucent white film containers?

I
read somewhere that PVC is bad for coins. How do I tell if the plastic

is
PVC?

Thanks,
David

The best-looking copper orphans all receive luxury lodgings. I cut a
slot in the top of an (empty) spaghetti sauce jar.

I had a very black buffalo nickel soaking for some months in olive oil.
It lightened it but I don't think it helped it. It is now a very dark grey.
Maybe another few months would help.

I have seen a few black buffalo nickels off and on
for over 30 years and don't understand what happened to them.

A key reason for the color may be silicon in the alloy. This will turn nickel
black. The silicon is found in the nickel ore and is difficult to remove.

Thanks Alan!
I never considered that it might come from within.
