Found two penny size coins that were pretty well coated with green "stuff". I tried putting them in vinegar/baking soda mixture hoping the green would disappear and I could determine type of coin as well as year. No such luck.....does anyone have any recommendations to get crusty green off of coin? I know they are copper because I accidentally scratched one.

Appeal to coinman123 and frankn. They both have wonderful safe coin cleaning methods.
I on the other hand, nearly blow up microwaves attempting to clean coins. ;)

I know many use the hot peroxide boil method, I have with limited success.

Baja mentioned ultrasonic cleaning, and from what I've seen it blows every other method out of the water.

Sorry I'm a little late.

Vinager won't help, just pit the coin worse. I would try putting it in boiling Hydrogen Peroxide, the stuff in a brown bottle you use to clean cuts, on them. Just put them in for a few minutes, and scrape the crust off with just fingernail or a toothpick or Q-Tip, then rub some olive oil or mineral oil on it to keep it moist, the peroxide drys out the coins. Just be careful, some coins have an ugly crust and when you remove it the coin looks incredible, other times the coin has pitted underneath the crust. Also, Many dug old coins have an attractive green patina, with if removed makes the coin look pitted and worse than before. Based on what I think, cleaning is worth a shot. I hope you have an Indian, good luck :thumbsup:

If it's that crusty, I would try a short blast of Electrolysis or two. 15 minutes max. then look at it. If necessary do another 10 to 15 minutes. Repeat if necessary. My 1st IHP was really crusty and I tried other methods, nothing worked so I used ELectrolysis.
