Hey Tony,
I just read this thread for the first time. I don't get on the Explorer Forum too often.
Living in Michigan also, I often feel your frustration! The state a detectorist lives in is a huge factor in what's in the ground to be found, IMO.
The east coast, from north to south, contains our nation's earliest history, and dropped items of value. It's the beginning point of our country, and the arrival point of millions of people during the westward expansion. Detectorist's in those historic locations have a treasure trove of history under their feet. Then there's our state. Being peninsula's, upper/lower, we weren't on a direct line of that expansion route of stagecoaches and wagontrains, etc., dropping valuables along the way, unfortunately! Our richest history is during the industrialization time. Not to suggest that there isn't some fantastic things to be found here.
Finding 1700's coins here, while not unheard of, is rare indeed! My oldest coin to date, is an 1847 half dime, and I was/am thrilled to have found one that old, and the other 1800's coins I was fortunate enough to find. I see you have found several gold rings, and silver coins, so it looks like some good fortune has come your way. Old silver coins are a greatly diminished resource now. Over the last several yrs, I have found more gold/silver rings/jewelry, than 1800's coins by a wide margin. Folks have been searching for those old coins with detectors for 50+ yrs. I first detected as a kid with my dad around 1970'ish. Even with the old BFO machine he started with, there WAS a lot of old silver to be had. The times they are a changin! I guess we gotta take what we can get.
For every nice find posted, there are thousands of detectorist's who walk away from a detecting session with a handful of clad, trinkets, and junk. That's the reality, it ain't getting no easier, that's for sure!
A lot of successful detectorist's spend a good deal of time reasearching undetected locations, which I also do during the winter months. I also visit a retired friend out west, who has access to old gold tailing piles on private property. I find a few little picker nuggets, and enjoy the heck out of it. I would love to nugget hunt more often, it's hard work, but really enjoyable! I guess we kind of have to make our own detecting adventures nowadays. Expand our detecting horizons as it were. There's an amazingly large amount of people getting into detecting over the yrs. Most don't stick with it too long because of the realities of the amount of time spent searching, to quality finds ratio, isn't that great. I guess it's the enjoyment of searching, with that possibilty of the nice old coin, or gold ring, that keeps many of us going.
Keep at it Tony, and good luck!
