Can anybody show some not so obvious examples of PVC? I'm having trouble seeing it.

Green PVC is often mentioned; but, are there other examples of PVC?

    There's a gunky haze that forms over the surface. It's a bit hard to show in a photo, but in a good grading class, with a good instructor, with good light, you'll quickly learn how to see it.

    I did this one thread.

    And then in this one I took one picture with the page tilted up to show some on the edges and a little on surface.

    Is this PVC to the right of the roof top and at the bottom of the coin? And also next to the left tree truck

    I am not seeing anything I associate with pvc on that coin. Others might see it though.
    What I see are some dark / black spots. Sometimes carbon spot is over used to describe dark spots. Probably something got on the coin at some point.

    A soak in acetone will dissolve pvc residue and will not affect the the coins general appearance. Good luck.

    PVC can appear as a brown splotch on the surface as well. Acetone soak does the job unless it's been on the coin so long it's done damage.

    If you do what you always did, you get what you always got.

    PVC appears different on different metals and also with the amount and length of time it has been on the coin. When buying raw coins, it is always best to give them an acetone bath when received, even if there is no obvious residue at that time. The acetone will not harm the metal and will not remove tarnish.... just organic residues. Cheers, RickO

    In some cases you can tilt the coin so you are practically seeing it edge-on. Any film present will reveal itself as a greenish-white haze. Look to the highest points of the coin that most likely touched the plastic holder.

    I've been lucky to not have purchased many Morgans with PVC but here is 1 with not so obvious PVC. It was in an NGC XF holder that I didn't even notice when I bot. Probably had the holder 10 years before I cracked the slab. I was upgrading dates and broke out for my Dansco. I soaked for a few days in acetone and it disappeared. Not sure if it would have grown any more in the slab. It is above Liberty's eye.

    That's what I'm talking about!

    So it was black? Did you know it was PVC before you put it in acetone? How was it different from the dark areas in the R & B above Miss Liberty?

    I'll grab some pics. We get lots of stuff with PVC that I have to remove.

    Actually it was a dull green, hard to see in pic. Maybe did not grow from limited exposure, but definitely PVC. Don't have a pic of coin tilted to see better. Was not as neon colored as some obvious examples, like the Lincoln above. Had some PVC on WLHs that were more obvious but already soaked in acetone.

    Just to clarify, it is not the black dirt in the corner of the eye but the lower part above the eye lid.
