I think there are way more coins beyond the depth capabilities of the modern detector than are in the depth range. I've hunted way too many prime old spots that I know have never been detected and have come up with little to nothing. I have done very well since starting back up after not detecting for probably 15 years but I did far better back in the early 80s when I first started. Back then most of the silver coin finds were in the 5-7 inch range so I imagine if they were that deep then they are quite a bit deeper now.When you think about it, back then mercury dimes had only been out of circulation 35 years and silver rosies and washingtons 16 years.
