This (at the time) was the third oldest American silver coin I have found (4th oldest now), an 1853 three cent piece, or “trime”. Its in pretty good shape, save for a little corrosion. This was at an old house with tons of iron, and it was not a very good signal; CO 33 or so on the E-Trac after an iron null. Not a signal I would dig too often at a park or school, but I was glad I did. 4-5 inches deep.
