I got this coin back in December .. Hoping I could help it out a little. Any thoughts on what you might try. I do have some before and after pictures. The after are not that much better. But I am curious what others might try   |

Wow! That one may be a goner. I always try to conserve badly corroded large cents but some are too far gone. Try an acetone soak followed by a soak in xylene. According to BadThad that's sort of a one, two punch. If the corrosion does come away soak it Verdi-Care and see what the result is. Unfortunately a lot of times even when you do remove the corrosion heavy pitting is left behind. Good luck.  |

 Pretty sure it's damage due to outdoor elements. being that it's copper makes it just about Impossible to fix. however I would try peroxide as some members have suggested in past posts.  |

I'm not sure what could be done or if anything would help. I'm interested on seeing the after pictures and method used.  |

Well I would say that is an improvement. What did you do to make it better?

To me it is still a long ways from being acceptable.
Have been doing about everything mentioned.
It might be at the point .. to make it a pocket piece.
Just thought I would see if there were any suggestion
I have forgot about .. or not tried.
It is no big deal .. I really don't have any money in it.
Just trying to make it better than it was.

Put it in the oven at 450. 15 minutes or so, that should get rid of that black corrosion on the coin. I don't see any active green corrosion so it should come out OK. If the black corrosion doesn't come off, you may need to use a Bunsen burner to get rid of it, only fire can stop active corrosion by producing Cu2O/CuO Cuprous/Cupric Oxide which will burn off from the surface of the coin. If the corrosion has eaten into the coin, it will leave the surfaces pitted. It does not appear that the black corrosion has eaten into the surface of your coin, so, you should be OK.

That's a great coin to experiment on. I like the details on it, and you've gotten some good suggestions. I'm tempted to pressure wash a really cruddy large Cent |

I've used xylene, by mistake, indoors.
I will never use this chemical again. Absolutely atrocious!

Quite an improvement from where you started. I'd like to see pics of your other attempts.

If you are doing things as an experiment maybe try to use iron out. I have a lot of iron in my water and I have to use it to clean my toilets once in a while. It works great and I don't have to scrub to get the rust residue off. It's a powder and all you would have to do is put the coin in a bowel of water and put some iron out in with it and watch the rust disappear. I don't know if it will have any effect on copper but might be worth a shot. http://www.walmart.com/ip/17133842?...edirect=true |
