Flips With PVC

A couple of years ago I decided to put my miscellaneous coins into plastic flips. The dealer who sold me the flips didn't mention they had PVC and would damage my coins over a period of time. How long does it take for the coins to be damaged? So far, as I switch the coins to safety flips, it doesn't seem the damage is major.

Depending on the amount of coins you had in those flips, you can toss them in some acetone for a bit just to be sure there isnt any residue.

 

Thanks. What all is acetone use for? I notice it is mentioned quite a bit.

 

PVC contamination rates very with temperature and humidity it is exposed to higher both are the faster it is.
Acetone has been discussed quite a few times but the quick and dirty is it is a highly flammable solvent that removes PVC with little effort. It will dissolve almost any plastic so use glass or metal containers and make sure their is plentifully ventilation and no spark sources in the area. Myself I wear Nitril gloves when using as there is a absorbency rick with continual expose. I buy both the gloves and Acetone in the paint dept. at Wall Mart.

Edit to add that once the PVC is on the coin the damage will continue even when removed from the old flip and will contaminate the new safe flip if not removed before installation.

It can get to be very expensive as I found out.

 

PVC damage can happen in the matter of months. Im not sure why some dealers still sell these and use them. Ive seen some very rare coins in PVC flips! And When I tell them, they dont seem to care...

 

1. They are less expensive than non-pvc flips.

2. PVC flips are softer ( until they get aged and start to crack ) and thus there is a lesser chance for the coin to be damaged, moving around in the flip or removing or inserting it, especially if it is being handled at a show. There are a few dealers than ship in a sealed PVC holder and put on a label that says after purchase is settled, move to a safe holder.

 

And there is another reason dealers use them. They do not scratch the coins as badly as the stiffer flips do. With all of the shaking/shifting in transit, that may be a real good thing.
