1969 Coins PVC Issues.

The mint set packaging was four layers and the coins went in the middle. The interior two layers are exceedingly thin but do contain PVC. You can see this when the plastic delaminates in bad storage. It's getting more and more common to find this delamination but it's still seen only infrequently.

I'm guessing the damage to the coins doesn't look like typical PVC damage because there is so very little PVC. It does still cause irreparable damage even in tiny amounts.

Coins should be removed from the mint sets and this especially applies to coins from the sets listed in the other thread.

If you must store coins in the packaging you might be able to do so longer if the sets are stored under ideal conditions (steady temperature and low humidity) and stored vertically in the paper sleeves. I believe these will go bad as well but it will take longer. So many are already ruined that it's just heartbreaking and I don't want to risk losing more of my coins.

'60 proof sets are relatively stable. I never said they were not.

Mint sets are less stable and the '69 to '84 are least stable.

I don't trust any mint packaging any longer but some like 1980 proof sets show no signs of deterioration.

This whole thing with PVC is kind of unsettling specially if you've spent 130.00 in fees and your return is zero....no holder, no box to add insult to injury.
I'll be removing my mint sets, it breaks my heart, but it will break my pocket much more.

I sent some 50s to 60s proof sets to ANACS for conservation and grading. The cellophane had degraded and it looks like there were layers to it. The coins looked like they were covered in a film. I posted pics on here after taking them out of the packaging, but before mailing them in. Many people thought they were damaged or pitted. I knew it was surface issues. They came back looking great. Graded anywhere from a proof 65 to 69. And as shiny as the day they left the mint. The only one that still had some issues was a Franklin from a set that developed holes in the cellophane. Causing carbon spotting. The carbon spotting was much lighter after conservation, but not completely gone.

I was already sending in another coin to ANACS for conservation. And they charge a flat fee per submission. Up to 20 coins for $39. Sent in three proof sets plus 5 other coins. So essentially $1.95 per coin for conservation. And it was during one of their specials so grading was only $10, and free return shipping.

Was it worth it on the penny and nickel, probably not, but I liked keeping the sets together. And doing something with them before the mint packaging did any more damage.

Trying the same thing with either of the big two would be cost prohibitive. Just sharing my experience. Maybe some people wanting to preserve old mint or proof set might consider. Also works great with uncirculated Ikes in the blue pack. Those also develop a very hazy coating.

!971 Ike packaging is also very unstable.

It will work.

As soon as you put it in the haze will disappear but let it soak anyway or it will come right back. You can always put them back in but it's easier to just let it go 24 hours and do it once. Bad ones will take 4 to 7 days if it works.

There is another means to restore coins that won't clean up but it is a last resort because it will destroy large numbers of coins; it makes them look cleaned ofttimes.

Good luck (but you shouldn't need it in this case).

CLADKING...All of your tips are keepers.
For those who dont believe that PVC is present in mint packages, speaking for the 1969s mint set that I own....Here is an image of that package, its green in color and has some hazing.
