I've read lots of posts on cleaning coins and what not to do and what to do. Just need verification on best method. These are not valuable coins. Indian Head Pennies fine to very fine. Should I use distilled water first to loosen up the crud and then work with a Q-tip or tooth pic then acetone and maybe if necessary xylene? Posting an example.

appreciate the help

Personal preference. Why not as long as you are keeping the patina and toning intact.

to CCF. I think I would start with acetone and be gentle of course. Maybe post a before and after photo.

If you start picking at the crud, the patina can come off with the crud....trust me. Do what you want, it's your coin.

You also need to consider the danger of working with aromatic hydrocarbons. They can build up fumes and cause breathing problems or reach a saturation level in the air that could cause a fire or explosion.

I don't like dirty coins, but I won't buy coins that have been cleaned. It's easy to see cleaned surfaces on coins.

I agree with Yukozuna. I use both Acetone and Xylene and this is especially true of Xylene. Be very careful.

I have used a lock pick to scrape away some of the bigger crud on my coins. Doesn't hurt it, and doesn't use chemicals

@LG, first welcome to CCF. Second, as a general rule, I would advise against anything more than an acetone bath, with no mechanical rubbing, picking, or scraping of anything on the coin's surface. What looks improved to you, may remove much of the value of the coins, even knowing that these are not super-valuable. For context, I have a whole bunch of foreign coins that my grandfather whizzed in the 1950s and 1960s that are now pretty much just hole-fillers. I'm not saying that what you are proposing is equivalent, but maybe just take it a little slow, ok?

You can't go back to original after ANY type of mechanical (with a tool) cleaning or anything other than pure Acetone.

The vast majority of collectors prefer original coins.

May as well use a sandblaster machine. Or some jewelry cleaner from Walmart. That coin is OK as is.
Rest in Peace

T-BOP, I don't really have this coin any longer to be able to post a picture of the obverse but I do have quite a few that are in the same dirty condition. I was just using this one as a good example. I'll just use the acetone with Q-tip and leave it as is after that.

Appreciate it and all the other replies and suggestions.

Those Indians took over 100 years to develop their patina. Might as well use a sand blaster as just carl suggested.
