Reading your reply made me think about the site, and wishing I could go back and hunt it again.
I know now how rare it is to find a hunt site like that. Like I said before when I first started hunting it
I was digging a lot of silver, I big part of that was there were so many coins and so few trash item that
I was only digging the higher reading signals. If the meter read penny or lower I went on. You have to imagine
a site that has mowed grass, all the old buildings and side walks. There would be little walk paths where you would see stone benches with inscriptions like Class of 1910. I first started hunting the ball field and PT area, I had a small map of the area, showing how it looked as military base in the 1940's. The 40's was it's busiest time. The ball fields started out being the best area, hunting the sidelines where people would sit and watch the games. Imagine a few coins falling out here and there,while they sat and watched the game
It turned out the bus stops were the best, there the coins were more concentrated in smaller areas, and seems like more multiple pockets of coins. I remember cutting one plug and seeing six mercury dimes fall out. I also remember one hole where I dug down 8 or 10 inches to find three coins, they were all touching in one little pile, the cool part was, one was a 1945 silver 20 centavos Filipinas, 1897 large British penny and a Copper Mexican coin. Just was neat to find three coin from different countries like that.
Now looking back where I was getting a lot of silver the first several time hunting that site, then it started getting harder to find the silver, I remember telling guys from a club I was in that I was not getting as much silver and had to start digging the penny signals. I was sort of new and I guess I thought finding sites like that would be easy.
I guess having those memories is part of what makes this hobby so great.
