Loving my new Nox800. Have been all over my frequent hunting grounds this week learning the ins and outs of the detector and different sounds. This is my first old find. The coin was so crusty I opted to clean it with electrolysis to bring out the details.
Make sure you don't use salt, it can create a toxic gas. I use Washing Soda to mix in with the water and to rub the coin. A few minutes in the bath with current then rub with washing soda. Repeat till happy with clean level.
