Hi I have dug lots of civil war coins in camps plus 4 gold dollars, the trick is you have to find early camps 1862 and before. After mid 62 they were using scrip money{ paper} and the silver and gold were not used. Only some held on to the coin money but mostly large cents, Indians and some small 3 cents pieces. So look for mid 62 and earlier camps to improve your coin count. I still hunt camps that have been pounded to death in the hay day of Relic hunting for the purpose to sell them. The old camps still have coins in them, but you must be using dd coils and a fast processing machine. Hunt in { 0 } discm and dig the iffy and Miltie tone signals, and you find many non ferrous targets co located with the ferrous that you would have never heard if using more discm. I have written on this before just look it up and yes I use a F 75, 4 tones, 0 discm as much sen that you can use and keep track of ground balance, yes it is mind crazy listening to it but it will pay off.
