FoodSaver vacumn machine-coin storage

Lightside

Has anybody tried out this method of coin storage?

I was thinking of storing Silver proof sets in these vacumn bags.


I also have volume 1 of the state quarter comm Dansco ms, proof clad, silver proof (4 sets) that I want to store for my grandkids future.

Can the plastic affect the quality of the proof coins if the proof sets are in the boxes?

Thanks for any ideas and comments.

Because the plastic is soft and not hard, I would be concered about PVC leaching on to the coin.

What he said.

You should make absolutely certain the plastic you are sealing the coins with does not contain PVC (polyvinyl chloride).

If the plastic is safe for food it should not contain any PVC, right?

I don't think any food grade stuff contains PVC. Of course, you should check this out.

I'm sure this response was very helpful.

Do that apply even if you wrap the slabs, albums, etc. in some sort of safe container before sealing?

I put a roll of ASE in a bag back in 1990 and vacumn sealed it
I opened it about 2 months ago and the coin are still blast white
But they where put in the Gov tube that they came in then sealed
Hope this helps I also put two Morgans in another bag back in 90 and have not opened it and the coins seem to now have a golden tone to them

Some day some entrepreneur will market a vacuum box large enough to store a collection. It doesn't even have to be a vacuum. It could simply be filled with helium.

I was thinking of putting dissiccant capsules in with the coins, vacumn seal the plastic bag and store the coins in a safe, cool place.

I would think that if the coins were in a box or container, than vacumn sealed, they would be safe.

Thanks for all the great ideas and tips......I will take heed to all your advice.

there is a simple test to determine if there is PVC in the plastic.

Light up a small propane burner, the kind you use for heating copper pipes, etc. in your workshop and take a little copper wire (held by a tool, not by your hand!) and heat it up and then melt a little bit of the plastic onto it. Make sure you have enough melted plastic on the copper wire.

Then insert the copper wire with the melted plastic right into the blue flame. The flame should remain blue if there is no PVC. If there is any PVC the flame will turn green (the same color that you see when PVC oozes onto the coins).

A second test. Simply take a match to the plastic bag or pouch over your kitchen sink. If the plastic burns with black or dark smoke, do not use it even if no PVC is contained. If there is white or what appears to be clear smoke then move onto the propane/copper test.

The plastic does not have PVC in it. It isn't a permanent hermetic seal so after a while it would start to let in the outside air. And, yes, I have thought of it. But I have not done it yet.
