Still it warrants some spectrum anaylzer testing for example set up some kind of receiver between two gold coins, use a sensitive magnetic detection circuit and run the analyzer through it paces. Maybe even stimulate one of the gold coins with a frequency or a lot of frequencies. Might be a pony in all the HS. 
If it was dowsing then I understand the gold as "witness" idea and have seen dowsers find samples where someone in the group knows there it is. The real goal is to find those hidden zillion we all dream of.

Hi goldfinder,
In many ways I think you are right. To begin, let's make a distinction between dowsing methods using samples and electronic methods using samples. In the case of dowsing while using a sample, there is no discussion other than the skeptical viewpoint of "trick of mind" and the believer viewpoint of "I saw it work". So this leaves us with a discussion of the electronic metal locators which use a sample placed near the receiver coil.
Your opinion of this kind of locator is:
"...Still it warrants some spectrum anaylzer testing for example set up some kind of receiver between two gold coins, use a sensitive magnetic detection circuit and run the analyzer through it paces. Maybe even stimulate one of the gold coins with a frequency or a lot of frequencies..."
This sounds like an interesting experiment to me. I suspect that if you were to perform this test you would discover there is no frequency which shows any special resonance to any particular metal. But it is still a good experiment to perform in order to confirm that what I suspect is correct or is incorrect. I would think it is a good idea to place a spectrum analyzer in an electrically clean environment and see what kind of frequencies you can find with nothing there. Then introduce a signal generator and see what you detect as the generator is moved from 1 Hz to the MHz range. Then repeat the experiment again when gold coins are placed in the same electrically clean environment. Then we can follow up by placing coins that are made of other metal alloys.
This should give some good information to work with for future reference.
Best wishes,
