View Full Version : Need help retoning a cleaned coin

I recently picked up a harshly cleaned large cent and was wondering if anyone offers a recoloring service for these.

You might send an email to Robert Dunfield, see link below.
I have never used his service so I can't testify to the quality of his work, simply pointing you in his direction.

I just looked at the photos provided and what's funny (funny for lack of a better word on my part) is the original coins shown before preservation look more desirable to me than the recolored. I guess to each their own. I figure that unless you're in a hurry an LC will re-tone in time.

Boy, I don't know if my "thinking cap" was on the first time I viewed Robert Dunfields examples of his work. The coins look very nice!!! Does anyone know if this is a long term process for him, or does it just take a relatively short time depending on his schedule?

Unfortunately Mr. Dunfield passed away in 2010. He was a fine gentleman. I bought several coppers from him over the years.

Oh, sorry to hear that....Has someone picked up where he left off?

Whether or not recoloring should be attempted depends pretty much on what the coin looks like now. Is it low or high grade? Corroded or otherwise smooth? Without seeing the coin (pictures at least), it's impossible to give good advice. If the coin is smooth and higher grade, I wouldn't recommend recoloring at all. If it's lower grade and/or corroded, it's probably OK to do it.
Keep in mind, however, that recoloring is an iffy process at best. Even in skilled hands, it only gives satisfactory results sometimes. All methods I have heard of use sulfur, which reacts chemically with copper, further corroding the surface of the coin. If you use very little and stop the process before you think it is done, sometimes you can get pretty good results. However, if you let it get too dark, the sulfur will microscopically pit the surface of the coin, making it worse than before it was recolored.
I know a number of people (including dealers) who recolor coins with sulfur ointment. That should be used ONLY for retouching small high points that are too bright for the rest of the coin.
Use any of these products at your own risk.
