I've done it twice, both successful. I used a dateless capped bust dime, and a dateless Barber quarter. Pulled dates and MMs off of the coins, and the Barber quarter was a semi-key date (1909 O). All I did was fill a little jar with two parts vinegar and one part hydrogen peroxide. I do not recommend you fill it up to the top, about 75% of the way will do. Then, I just waited a few hours. Took a full 24 hours for the capped bust dime, as literally the only thing you could see on it before was a small part of the eagle. Before and after pictures: Before:   After:   EDIT: cant find the pics of the dime, will have to look later. |

COTW, I thought it was funny why everyone was correcting you on the other thread about the 1916 D dime, I knew that you knew your stuff!!!
Thank you for sharing!

Well, I guess I stand corrected!  But tell me, you say before and after pictures, but these look more like obverse and reverse pictures.  |

That's amazing.......I think the general thought on the forum was that it couldn't be done, and this is the first I've heard of it. Thanks.

Be extremely careful if you are mixing these two chemicals, they create peracetic acid which if the vapors are inhaled can permanantly damage your lungs

I posted a couple of years back that my dad had a S.L. quarter set with many acid dates, and I was told that it was impossible. I never replied back. I personally have never done this, but will the dates remain for long, or do they also wear off? I pulled out my Buffalo nickel book set that I hadn't looked at in years, but with my failing eyesight, I couldn't read many of the dates any longer. Granted this was from wear, not acid. |

Post pictures of your nickels before you put acid on them.
I tried this on some silver, but it didn't work.

Yes, it can be done, but why? There is little numismatic value there. If it happened to be a rare one like a 1916 Standing Liberty quarter, the acid date could lower the value. Those coins can be identified by the bottom folds in Ms. Liberty's skirt. Coin authentication is not always as simple as it might seem. Edited by billjones

What about the 1921 and 23s? People would pay up for those

Ferric chloride is the main chemical in the stuff used to pull dates off of dateless nickels. It attacks COPPER... 75 percent of nickels, 10 percent of junk silver. Should work on junk silver.

They are still better than dateless coins. I'm amazed this can be done. How does the coin feel afterwards...is it rough?

I agree briank ,since they have a little or no value,they are better than dateless coins.

The way this works on any coin is via a metal etchant, peracetic acid can etch silver but doesn't work as fast as nitric acid does. There are metal etchant acids for every type of metal, you could technically bring back the date on a gold coin via the same method using aqua regia but thats even more dangerous than the silver etchants are.
