I have a copy that came with the detector. I think it will take me some time on the audio. Which audio mode do you run in most of the time? Also do you run in high trash mode or low trash? This forum has been a real big help. I'm not finding alot of older coins but I am finding some and I'm mainly hunting schoolyards that have been hammered for years.
That sounds pretty safe to me. I'm not sure how much dirt it would get off, but I'll sure try it, and it does sound pretty safe. Did somebody say peroxide in some way or form. I thought I heard that, but I'm not sure. At any rate, I'm glad were still addressing this issue from time to time because I think it's so important, and, you know, after all is said and done, I would think that the coin store guy is the most important one to please or at least another buyer out there. If the coin store guy is happy, then we'd probably be happy too, if you get my drift. I had very good luck with the electrolysis type method, but it really worries me if I'm taking off too much stuff and changing the color and look of the coin too much. That one needs more investigation, at least on my part.
