Unlucky Totally f*#ked would be the grade I would give it. Not much you can do now to save it. I think even if you stripped it back with acid or something it would still leave pitting where the corrosion was.

when I first got it, the crown could not be seen at all, and the one half was tottaly covered, so the old tooth brush has removed some, but not enough. next time this is seen it might be cleaned, just to try and save it :(

ok, played with a less important coin or 2
vinegar helped by itself, adding a pinch of salt is a no no.
peroxide removed most, but spoiled the colour and opened up the pitting.
el cheapo engine degreaser, worked ok, removed grime with the help of the toothbrush, and knocked the top of the green crap, no signs of pitting yet but its not all gone yet.
a few coins covered in fire soot damage, cleaned up a bit with just peroxide, but what it didnt lift looks like its almost part of the coin, but it did dis colour the 5cent piece badly. not the coppers, just gave them a bright appearance.

I have found that if I soak copper coins in vinegar for about 10 mins it removes a lot of the verd and then the rest can be removed with a toothbrush.
I still had big issues with ugly indents left where the corrosion was.
After I removed all the crap with vinegar I boiled the coins (outside the house) in water mixed with brown shoe polish (sounds crazy) which put on a pretty good layer of 'toning' that was actually pretty close to natural.
Im assuming you havent started on the halfpenny posted and it would be pretty good if you could clean this coin up a bit. When you have a go with it please post another pic.

If you're going to so much effort to revive the "goner" coin. I wonder if you will keep the original picture to disclose the state of the coin when you eventually sell it?
To me, that's a coin for the bin.

yep I am going to keep experimenting to find something to save it, been thinking of the stop rust paint, as many of the ebay pennies have the glossy sheen that it gives, and yes if I'm successful and sell it I will say I cleaned it, and saved it from green cancer. problem is there is over 100 coins I havnt seen yet that are ranging from ok to worse than ^^. and if I can save em I will try and buy the rest |

You mentioned fire damage. The blobs on the coin may be melted plastic have a Google and see what will remove that. Try a petrol dip or thinners, If that dosn't work try brake fluid ( I know brake fluid will remove paint from metal). Give it a go but at the end of the day you will end up with a "Cleaned coin" that nobody realy wants in their collection. Best of luck with your endevours  |

it could be plastic layered on a couple, I havnt looked at the with the big glass since I started cleaning but with the small mag glass it looks attached. if it is plastic my next idea of steam might work, also putting 1 into olive oil today, and going to try a pressure cleaner on another. as I said I have a few damaged ones, shame some are key dates. some of these pennies might make up the difference of my $20 over buy last night,
