While working on my mom's home, I came across my dad's coin collection in two pipe tobacco cans. Our own tin-can hoard!
Nothing valuable in the lot, but my mom wants me to divide them up among my siblings, so that we can give them to our kids - or whatever we choose.
The problem is that unlike the Saddle Ridge cans, these tin cans didn't protect the coins very well. There are a bunch of Ikes and SBAs that have powdery, green verdigris. I've never seen verdigris on clad coins. So my question is, can I do anything about this?
Again, none of these coins have numismatic value, but they would be great tooth fairy loot. My nieces and nephews have probably never seen dollar coins that are actually the size of silver dollar pancakes! So I'd like to clean them up a bit.
I appreciate any advice!

The green powder could be some form of layer from the tobacco renements in the can, try 100% acetone.

Try acetone and see if it does the job. Hopefully it's not as bad as I think it is...

The reason the gold coins did so well is they are gold.

Could we have pics of a few with the worst "verdigris" please? That might help us in determining what it is and hopefully has to get rid of it.

Yeah, I certainly will try acetone first thing when I get home. But this looks more like verdigris, perhaps like it was caused by moisture. Here are a couple of quick camera-phone pix:   |

Hmmm, interesting. Thanks for the pics, hope the acetone clears it up. If there's any changes after the soak could we have pics please?
Good luck and I think you'll have to leave the coin in for a while, try it on this coin first before so you can see the results first.
Good luck!

Oh and may I reccomend trying to pick of a majority of the gunk so the acetone can clear it up quicker.

I'm afraid there's irreversible damage under that much verdigris. Your only hope is a prolonged acetone dip.

Yeah - that does not look good!
Actually, verdigris is really common on clad coinage, often in the form of small spots. What you've got there is much worse.
Good luck!
