How do I clean uncleaned (dirty with patina) ancient Roman coins? with vinegar?

I have several uncleaned ancient roman bronze coins, and would like to clean them safely to remove the centuries-old patina and dirt. This is a project for me and my 4-yr old son. Thank you!

Cleaning artifacts can devalue them. I'd proceed with caution if you later plan to sell them. In any case, I'd begin with the most gentle methods and work up as needed.

I would start with plain old hot water. Put them in a glass baking dish and pour steaming but not quite boiling water on them. Stir gently with a wooden spoon and let soak for 15 minutes. Remove and swab dry with a fairly fluffy towel (a washcloth would be good).

The nice thing about using a sequence of cleaning techniques is that some coins won't need as much as others and also you get to appreciate the gradual revelation of detail.
