What Should I Do?

If they are PVC (They probvably are) Put them in acetone first.

There are a few silver mostly nickels and pennies( including a 14S and 24S)

I wouldn't bother unless you think they have already been affected by the plasticizer oils gassing out onto them, in direct contact with the PVC.

They should ALL be rehoused in a non PVC environment.

My experience is that the oils will affect the coins in PVC flips, but it has been only obviously noticeable over a period of years. Red Unc. bronze coins are the ones that are the most sensitive, so examine those most closely.

If you think some have been affected, put those in acetone, in a screw top sealed jar to save the acetone and to avoid fumimg yourself, and well away from a possible ignition source.

$5 for a 1oz bottle when acetone is $5/qt and leaves nothing behind to *be* detected? Heck, we're trying to decide whether the cost of acetone is justifiable here, not asking him to take a Q-tip to hundreds of coins one at a time.

Anyway, the primary worry here is PVC plasticizers, which that product does nothing for so all he'd be doing is spending extra money. Don't forgt, "green" is a later stage in the process. By the time something shows green, it's already been working for a while.

CRHer, this is a lot of work any way you look at it. I would be considering something allowing you to do the initial soak for a number of coins at a time. Heck, you're looking at close to 5 gallons of acetone to do it the way we normally recommend. Can you be sure the flips contain PVC plasticizers? That's not the only way to come up with a "soft" flip. Maybe we can get you out of the work.

I'm Curious when you "dump" the acetone after doing a dip, where are you all dumping it?

A great article about preserving your coins:

"Silica gel also can be beneficial, she reports. If
you've purchased a new camera or radio lately, you've
probably noticed a small packet of silica gel in the box.
Silica gel and silica are "very handy for maintaining a dry
environment," Maltby says. Basically, they serve as sponges,
drawing all the moisture out of the air.

Sue Maltby also recommends dipping your coins in a
neutral solution, such as alcohol, before storing them. For
his part, Bern Nagengast advises that you treat them with an
evaporative freon solution such as trichlorotrifluoroethane.
This protects the surfaces of your coins from environmental
damage, yet is harmless itself to the coins.

[Note: Since this article was first published, new production
of trichlorotrifluoroethane, a highly evaporative freon, was
banned because of its destructive effect on the earth's protective
ozone layer. And a superb new product designed to maintain and
protect coins, Intercept Shield, was introduced by John Albanese.]

--Maybe someone on here could get some from their shop & sell them to the CC members?

I just dump it onto the concrete driveway. It evaporates away in about a minute. Sometime when the pyro in me is acting up I light it after I dump it on the concrete and burn it off. (I wouldn't do that on asphalt though. The solvent action of the acetone might liberate enough hydrocarbons from the asphalt that you might be able to get it burning as well.)

If you want to make up your own packaging you can get silica gel a lot cheaper. For example the above has a 1 lb for $17 or 2 lb for $28 (plus $13.80 shipping). Here you can get five pounds of bulk indicating silica gel for $17 (plus $21 shipping).

The shipping is higher for the 5 pounds but the 2 pound works out to $21 a pound and the five pound works out to $7.60 a pound.
