Yesterday was my first time out in over a month. Hit a couple of schools without much luck and was about ready to head home. I decided to follow a grass patch outside the school and was digging every high tone. 12.44 beside a big pine I figured would be another 70s penny. Popped the plug and a crusty old one dime looking at me. It was in pretty bad shape and took a hard scrub to get the crud off. It's my third 1901 dime and still can't get an S mint mark. Still a nice surprise beside a 1950's school. Good luck guys.
