No need a new thread - over 3 decades of detecting for typical coins (silver not as abundant as years past but still find them), trash, tokens, jewelery, trash, relics (no civil war relics where I'm at - but some old mining town junk), trash, knifes, trash, watches, trash, keys, trash, and such a wide variety of all kinds of odds & ends, and a ton of trash.
My point - some folks will cherry pick by trying to discriminate all but common coins and those are the folks that miss a lot. That's okay I guess, but as stated, I dig up a ton of trash because much jewelery etc., fall in trash range. Small coils and go slow is what I do for the trashy areas, but I'll knock out the trash if time is short.
It's just a hobby that gets me out sometimes - I'm not really a coin collector although I don't pass digging up a coin signal, not even a penny. Although I know nothing about coins, it brings a smile still when I dig up a large cent, Indian head, standing/walkers etc.
The far and few in between - gold coins, silver dollars, halfs, US 2-cent, US 3-cent, half dimes etc.
But it's fun trying. Take the dogs out, sometimes the kids, friends etc - its just a hobby but one that puts time into it and has patience are hopefully successful instead of some I seen get their hopes high and get discouraged.
