Vacuum-packed coins

Have you ever tried this practice/ how are the lasting results?

Shamika

Never tried it, but assuming the coin surfaces are clean, it should completely stabilize the coin during the duration of the vacuum.

Do you know if there is PVC in the plastic used with the vacuum packs?

***poof***
It was easier to put up preserves...
no, I have not tried this process, it
was discussed here about 3-4 weeks
ago...don't remember title, but raw coins in
clad or silver put into one of those provided
vacuum bags to me is unproven and unwise.
You'd have to get the chemical make up from
the mfg. Just about all soft plastics that will
mold like that have some poly vinyl chloride
to keep it flexible. Good question?

It was discussed a bit in this thread

It's my understanding that any plastic intended for food storage will not contain PVC. I have several coins in Capital holders that have been vacuum sealed for years using my Food Saver Vacuum Sealer and they are fine.

What About Consumer Packaging Materials?

Plastic Wraps and Storage Bags - Consumer plastic wraps and bags are made from three major categories of plastics: polyethylene (PE), polyvinylidene chloride (PVCD), and polyvinyl chloride (PVC). The plastic resins are petroleum derivatives. Plasticizers, colorants or anti-fog compounds may be added.


As long as the coins are inside other holders and no contact is made with the coin, no problem, but as I said previously, I wouldn't put a raw coin into a food storage bag and remove the atmosphere.
