I bought a 1858 VF-30 ICCS Large Cent about four months ago. I set it aside and looked more closely at it last week. Both sides seem to have a small amount "green" colour. No mention of that on the label. Did not see that on the ebay picture. Would it affect value? What is it? Will it get worse? I plan to open the seal and put it in my album eventually. I assume I should not try to remove the substance. I am happy with the grade otherwise. . Edited by punman

By the sounds of it, it could be PVC contamination. But there are other possibilities. Can you post pics?

Either PVC contamination.... or verdigris... both can be treatable.. but if it's verdigris it's basically corrosion... which you will need to address and perhaps someone else here can chime in on how to fix that a lot better...

punman if you remove the coin give a nice acetone bath ..This will remove the green and not damage the coin.. After you can give a quick rince with mineral water and let air dry... I have also heard of guys putting it in olive oil and or WD 40 after the bath...

I have heard of olive oil... I have also heard of vasoline .. But I just cringed at the thought of WD40. Go figure...

WD40 is quite good at removing soft green, brown and other goo from copper. It does not impact the copper surface.
I had a recent instance where I bought about 50 large cents which someone had thoughtfully (not!!) numbered with indelible red ink. Acetone did not remove the ink. But after a couple of days in WD 40 (it did take a couple of days).....not a trace. No impact on the surfaces at all.
Ivory dish soap after the fact can remove the WD40.

Peterbilt Chemicals product "COIN CARE" is amazing if used properly on copper bronze and copper nickel pieces. Comes in a two ounce can under 10 bucks US. Also remember hard green or brown crud means the coin is ruined!

So I can just use WD40 and skip the acetone?
I paid over $100 for this coin and don't want to damage it.
And by the way, what is the "green stuff"?

The green will either look moist or dry. If it looks dry you are out of luck in all likelihood. It probably indicates the underlying copper has been eaten. If the green looks moist it is is hopefully PVC damage that can be removed without any impact on the underlying copper.

Is your coin still in the holder?

Yes it is still in the holder.
All my other large cents are not graded and in my album.
I'd like to open this one up and put it in the album too unless I decide to sell this one. I really like this coin - apart from the green.

Whether it solves the problem or not, is the consensus that I could apply WD40 without damaging the coin?
