My detecting spots are mostly limited to public places. For some reason, I do not feel comfortable knocking on doors of people with old houses and asking to dig in their yards. Just about all of the coins over 150 year old that I have found have come from old houses of people that I know. The last large cents that I found came from a house built in 1830 and I found five of them. This was about 9 years ago. With my history done, here is the story. I have been detecting a school built in 1959 and it consists of a soccer field on one level, a football field on the next level, and a baseball field on the highest level. I have concentrated my efforts on the football field and I always hit the soccer field on my way out. I have been hunting this place for four years and have found over 50 silver coins and several hundred wheat pennies. All of the silver are roosies and a spattering of mercs. Last Sunday while hunting this spot, I started in the football field and had a normal for this place morning(five wheats and one silver roosie). After three hours of detecting I headed back to the truck and decided on one spin around the perimeter of the soccer field. I must have found about 7 or 8 clads. When I got about 3/4 of the way around the field, I got a nice signal that was deep. From about 11 inches deep comes a 183? large cent. I was amazed and figured it was brought in with fill. Since I was heading for home, I decided that the next time I was here I would grid the area to see what was left. I did not have too high of expectations because this was the first and only old coin from this school. Yesterday I was back and spent most of the morning in a part of the soccer field that produced wheats and silver. I was saving the large cent area for later in the morning. This particular area has a gate in the fence so I started my grid by detecting three fence posts each way from this gate. On the second pass, I got a reading on the Explorer which was where a clad quarter would hit and not all that deep. From 6 or 7 inches I saw the outline of a large cent sized coin and sure enough it was another one. Not nearly as deep and about ten feet from the first one I found. I really tightened my pattern and it was three or four passes later I got a "stop you dead in your tracks" silver signal. Explorer users know what I mean. From 6 or 7 inches I saw silver. I was expecting a silver roosie , but when I saw the back of the coin, I knew it was better. 1849 seated dime! I highly doubt that these coins came in fill, but am more inclined to believe there was something here 150 plus years ago. Less than twenty feet away from the seated, I found a 1956 roosie. You can bet I will be back and really gridding.
