Top ten ways to destroy coins PVC - Part 4

| Stan McDonald - author

PVC (polyvinylchloride) destroys the surface of a coin. Streaks, spots, a milky color, and other distractions are prevalent. PVC is found in plastics, such as coin flips.

For long-term storage, coins of value should be encased by the grading services, stored in airtight holders, coin albums designed to protect coins, or in gas containers.

I hope the photo is clear enough for you to see the damage. I have some "milky white" samples but I was not satisfied with the photos.

I had some Japanese mint sets from a the 70's that were sold in PVC laden holders. They were COVERED in green slime. They were not worth much more than their face value so I just cut them out of their tainted holder and threw them in with other junk foreign coins. Fortunately those holders are found very rarely nowadays and conservation can be done.

Bama's advice works. Since I've been collecting for forty plus years, some of my coins were stored in the earlier plastic flips mentioned. Acetone eliminated it on all but a few where on those magnification is needed to see the trace remnants. Another excellent product is Verdi-Care, if you can get it. Sold out and unavailable for months.

Pure Acetone might work, won't hurt

That nasty goop. Thanks.


Level 5

So many dangers for coins. I had a couple coins rejected for grading because of pvc. The coins did not show the pvc by just looking at them. Had these coins quite a long time. Any views on acetone for removing pvc?

If you never intend to have any of these coins encased by PCGS or NGC, there are cleaners made especially for silver coins so by major coin dealers. If you want to know where to get it, email me at: errorcoinexpert@aol.com
