Herre's a tip on cleaning corroded silver coins

Yesterday I found a heavily corroded 1853O silver dime. It was so corroded I thought it was a copper coin. Even after hitting it with soap and water. Picture one and two show the dime, yesterday, after scrubbing it hard with a toothbrush. I then soaked it for 24 hours in a solution of one cup of lemon juice and a tablespoon of salt. Today, I cleaned it again with a toothbrush and all the corrosion came off. I then polished it with warm water and Cream of Tartar. It's not a liquid, but a powder used in cooking. The dime isn't in the greatest shape, but it is now corrosion free. Thought you might like that tip in case you find a badly corroded coin.

Thanks for looking, and keep on diggin'

Nice clean-up. I use a Chicago tumbler, filled with aquarium rocks.
 
Great find and good tip jimmy. I never wanted to put silver coins in a rock thumbler so I just used toothbrush and soap and seldom with good results. Thanks, HH jim tn
 
Beautiful coin, Jimmy!

I've only found one SL dime so far, but it was severely corroded on the whole coin. Like the top part of the reverse on yours, a layer of corrosion on the whole coin.

Took me a lot of looking before I could figure out what it was.

Mine didn't turn out as well as yours, next time I'll try the lemon juice and salt.

Wonder if there's something about the composition of the seated liberty (other than a lot of years in the ground) that causes the corrosion. I've never dug another silver with corrosion like that.
 
I realize this is a very old post, but I am intrigued by this method. I recently dug a much newer .925 silver medal. I may have to try this method. Some of the corrosion is green on mine. Guess I cannot post a photo here because of size restrictions, but there are photos here:

that came out real nice!

i cleaned a silver half with toothpaste. i just put some Crest on it and rubbed it for a few minutes with my fingers, which quickly turned black. it wasn't in real bad shape to begin with, though.
