First Real Outing

I was detecting an old cellar site I presumed to be 1800s. When I got a decent 12-41 on the E-TRAC at 6 inches or so. I dug down and found a nail I  rescanned, there was still a target and out pops another nail and this coin!!!!! Definitely dated the site a lot older than I thought. I also found this 1700's buckle on the same day. The coin is a 1785 colonial Connecticut copper one cent coin!!! Did I mention this was the first real outing with the E-TRAC for me?
