PLEASE NOTE: This is only informational based on my experience. Be careful if attempting to do this for your own coins.

1. Spend a TON of time inspecting the artificially toned coin for hairlines, scratches, or damage underneath the toning. Use a black light and LED light, which often help bring out underlying hairlines

2.

Use dip diluted heavily with distilled water. I used about 20 parts water to 1 part E*Z*Est coin dip.

3. Apply by pouring it over the surfaces repeatedly.
