Wow, this is a super place to be detecting. So the town dumps it off and you are there to make sure all the dirt is cleaned of coins, jewelry and relics? If you are finding wheat cents, silver and other types of coins are very likely. I can safely say every place that I have ever hunted and found wheat cents I have always found other types of coins as well. (silver, IH cents, etc) I certainly wouldn't write the place off by any means. I can only dream of hunting a place like this. That is a lot of area to cover... If you need any help I can rake out the piles and assist with my detector....lol
Sometimes for me when I get feeling like how you are feeling, I will go hunt a total different property. While I am at this other hunt site, I will start thinking of ideas of how to hit the other site to make it produce again. Whether it be changing coils, angles that I hunt at, pick a total new area to hunt on the site, different detector settings, coil speed, different detector etc. I can say that doing this helps to keep the finds coming. As we all know, a site may be pounded heavily and left to die, but the truth is there will always be good things to find if we just tweak our mind set and try something different. (I am most certainly including myself here)
My brother proved this to me last year at an old carnival site. I hit this place almost every day and made it bleed with finds. I tried different coils and changed my detector settings and covered this field quite well or at least I thought I did... I had spent massive amounts of hours hunting this place. It had been hit to death by every detector imaginable over the years. I started to feel like there just wasn't anything left...like I was now wasting my time. Then one day my brother goes there by himself with one of the cheapest detectors on the market. (less then $100.00 detector) and pulls out this beautiful brass boy scout medallion. How in the @%$%# did I miss this I thought to myself. He finds it in the field in an area that I have focused & hunted a gazillion times myself. I started thinking to myself, was it because he had a concentric coil on his detector? Disc cranked to max? (which he did) He always swings his detector like he is cutting wheat in the field and his coil is 5" off the ground.
This took me by pleasant surprise and renewed my faith in this site and reminds me of the saying, "no site is truly ever hunted out"
With this site you are hunting, the place is always being "refreshed" with new dirt dug up from different places all over town. You couldn't ask for a better situation. At least that is how I feel of your situation. Hang in there matthias, your luck will change. - Jim
