I dont find many coins on my property but I find a lot of rocks that give off stong signals. Quartz I can identify and have found some but this one I have no idea what kind of rock it is. It has a few light shiny areas and many black pihead size areas. Any rock experts here? Thanks.
From what I can see. the pink looks to be a Feldspar and the tiny flecks are mica. If there are really dark spots, those might be tourmalines. What area was this collected in, if I may ask? Here in Colorado, Micaceous Feldspars are found in Pegmatite dikes, pretty common around here. Good luck and Happy Hunting.
They come from my yard in S.E. Wi. I am just curious why so many rocks set off my detector, I've gone elsewhere nearby and have'nt had any rocks give off a signal. Would any of the components you mentioned set off a detector? I know that about 100 yrs. ago there was an iron mine about 10 mi. from here, but thats a different situation, it's in the face of a cliff. Rocks comprise about 50% of the mass below the topsoil around here. Thanks for info.
