How to artificially/naturally tone a coin w/o chemicals

I have an 1881 Morgan Dollar and I wanted to tone it (it's been cleaned (not by me)) I want to have a rainbow-type tone on it... any advice?

    Tarnish is environmental damage to metal surfaces. It occurs naturally and artificially. Natural is liked by many collectors... and even artificial tarnish has been found to be attractive. If a TPG believes it is artificial, it will be labeled as Questionable Color (QC) and maybe details. Best advice is not to mess with your coins... in most cases, it can be detected. If you like colorful tarnish, there are plenty on the market. You will have no competition from me. Cheers, RickO
