See, I did the same thing as edweather, I didn't really think about the smell. I found a plastic spray bottle labled 'vinegar' and poured it in. Anyway, the yellowish rice vinegar didn't seem to do anything to the clad half dollar's color, so I went ahead with the nickels. They've been in for about 10 minutes and the D mint one is already developing lots of bubbles around it. I'll see how they are in the morning, and post pictures later tomorrow.

One is already showing up as 1916-D! Will leave it in to be sure, though.

Thanks. The other is showing signs of change now, so I'll probably have results posted by 5:45 tomorrow morning, for you and I. (8:45 forum time)

Took them both out again- other one is looking like a 1920, like I thought. Putting both in overnight, though.
They are developing some brown-yellow buildup that may be from the rice vinegar. It easily wipes off with a dry rag, but I don't want to rub off the date. Any suggestions?

Does it come off in water? If not you could gently brush it with a paper towel. Just be careful around the date. I guess I would go get distilled vinegar from the store if it continues.

We have white vinegar that I could use, I just didn't know that when I started. It came off when I put water on and lightly dabbed with a cloth. Anyway, they were each in for about 2 hours and I was worried at the end there that I had left them too long and the dates were gone. Luckily, in the right light I have confirmed the dates as... get ready... 1920 and 1916-D (wish that one was a Mercury dime). Curiously, the buildup only developed at the beginning, and when I took it off and put them back in for a couple hours it did not come back. |

Interesting. I have one more dateless buff I will soak when I get vinegar and peroxide today or tomorrow.

I remember seeing a 1916 quarter in at least a Fine grade years ago on ebay that someone acid dated (hopefully before the advent of the internet where the knowledge of die markers is now readily available saving many coin wrong doings)  There was a discussion about some product that was advertised in coin magazines back int eh 1960's t6hat was said to date silver coins which has long since been off the market. I have an SLQ somewhere that has been acid dated. I just saw this one on ebay which appears to have been acid dated by the same method however it doesn't look like a 1919 to me and with no larger pictures I would definitely stay away from this one. http://www.ebay.com/itm/1919-S-25C-....m2518.l4276 |

Nic-a-date is basically just hydrochloric acid diluted into a gel-like substrate to stop it flowing like water. It lets you put a blob of goo down right on the date-spot so you can leave the rest of the patina alone.
Whether this is "better" or "worse" than acid-treating the entire coin is a matter of artistic opinion; it is perhaps less potentially "deceptive", since a bright white spot around the date clearly labels it as having been acid-restored.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis

Ok, just put a super slick one in acid. I will get some peroxide tomorrow.

You can use etchants to bring back the dates on virtually any coin, the main problem is that for alot of metals the chemicals needed are nasty acids that will eat away your flesh if accidentally spill them. For example in theory you could use aqua regia to bring back the date on a dateless gold piece, but aqua regia is extremely corrosive!

Good luck on this one, SSK! It'll probably just be another 1916 DDO or 1918/7-D, but it's worth a shot.  |
