Sorry, but it's environmental damage and that kills any value. You can find damaged coins like this in dealer pick bins for 25-50 cent
If you don't get that green off of there, it will be worth nothing because it will get eaten up. At the very least soak this in water for a few days with brushing it with a toothbrush, then dry it in the oven on low for a couple of hours.
The condition of the cent would make it around the price paid if not for the damage and verdigris corrosion. Jim
I agree with the others...the coin is damaged and not worth the $2 paid. That being said, $2 is not a bad price for a coin to learn from. I'd keep it as is and study it...the damage is done and it's not worth conserving. Learn to identify what it is so you don't make the same error again. We've all done it and that's how we learn.
...except from the standpoint of soaking it in distilled water a few days, brushing it with a toothbrush (not the one you use for your teeth ) and then letting it dry out in an oven set at warm for a couple of hours. That would keep any corrosion from getting worse.
You could. But at what gain? This coin is toast. I’d leave it as is as an example for future purchases.
That's true. My only point was...that sometimes it's nice to have reference materials when you are learning. I consider pieces like this to be that. Sure, they can be cleaned up...there's nothing wrong with that. Either way is fine with me.
No offense but that doesn't look like toning to me. But I'm new to this so... But it looks more like age and rust...???
