I met my friend again after work to try the woods where I found my 2 cent coin. Still haven't found the foundation yet but are finding coins. I found my 3rd 1800 coin - a 1865 Indian penny - my first this year and my friend found the first silver - a 1893 Canadian dime. So now we know that there is silver there. Between us that's 4 1800 coins - he also found a wheat penny. We could find more once the weeds go down. We may try it again later in the week.
