I know, DON"T CLEAN, but...
I've read many of the postings admonishing one not to clean coins.
So, do you just leave coins with corrosion in 2x2s?
Don't they get worse or possibly contaminate other coins?
What do the preservation companies do?

Well, just Love coins, period.
Yes, do not put junk coins in the same album with "problem free". I have a feeling the PVC will see a new home and wreck it faster than SECTION 8ers. !

The posted coin is a perfect candidate for you to experiment with preservation. Search the threads for PVC, acetone, etc. and give it a go. I'd say you have nothing to lose with this particular coin. Be sure to post your efforts and results (and always include pics in a case like this).

Also stated was to not keep coins with active corrosion or PVC arond other coins - I agree with that. Why take unnecessary chances? Most of all, though, WELCOME!

Keep looking and collecting! Not much to worry about with those two. Certainly foreign
coins are worth collecting and we don't see them much so they can be hard to find locally.
Those examples are certainly not expensive coins and you could try just trading them for
coins without problems. Perhaps if you have a bunch of foreign coins you could sell them
as a lot on ebay. Just post a good pic of two (showing the problems) and sell them that
way. Use the money to find better examples that don't have the problems these have.
Regardless, keep collecting and always be on the lookout for new stuff!

Carefully removing verdigris or corrosion would be conservation.

Thank you all for the clarification.
Here is the problem that started me searching this forum.
A friend has a great number of Indian cents.
It seems they got wetter than he knew.
What is the best course to rescue whatever can be rescued from this?

Take some picture of some of the ones that you find and post them here.
This is conservation and not cleaning.
<< <i>That is a box on IHCs. Do not touch those with anything more than what is mentioned here. They are what they are. Take out the rolls one at a time and pull the nicest coins out of the tubes to eventually put 2x2's. Look for being able to read all or most of Liberty on anything before 1884 and the have the coin in uniform milk chocolate brown color and free of any PVC or spots. For coins that may have anything that looks like goop on them, give them a quick rinse in Acetone. Use the Acetone in a well ventlated place. Do not rub or touch the coin with anything more then a q-tip, and that should be done very gently with a dabbing motion and not a back and forth motion. Let air dry and then put in the 2x2's.

Also, don't use acetone anywhere near a flame.

He did mention that "they got wetter than he knew". Copper+water=the potential of all sorts of nasty things to the coins.
You may want to get them out of the tubes to air dry... Soon. Lay them out on a soft surface and do not rub them. Take a few photos and report back here.

Thank you all for the welcome and advice.
I should say I was speculating when I said the coins got wet. A freind is selling them and was surprised when he pulled them out and we saw all the corrosion. I don't really know how it happened.
He sent them home with me to sort and salvage what I could before we decide on a fair price
The good news is the coins aren't high end. Most seem to be goods with a lesser number of fines.
I saw this auction on ebay:

Do people actully buy coins in that condition? Is there no way to at least neutralize the corrosion?
The arrest of growth of the substance we know as verdigris is not going to be helped by treating the coin that has such on it with acetone.Acetone is useful to remove some things that get on coins but verdigris is not one of them.Having said that,there is nothing wrong with treating these IHC's with acetone.Definitely avoid using water.
There is nothing,as far as I know,that one can do to remove spots or patches of verdigris (salts of copper) on a coin without noticeably and adversely affecting the appearance of the coin.
Coins that have gotten wet and have begun to corrode like these Indian cents are pretty much goners.
Of course,better date or key IHC would get more money for the owner but should be left alone.Any attempt to remove the corrosion will most likely make the piece even more undesireable to a collector and will most certainly decrease its value even more.

There are some nice coins in the lot. This picture brings a tear to my eye:
WOW, Frankcoins. That looks like it should take off anything!

No doubt you where drunk at the time?
