I tried out a new park this morning before it got too hot out. The park itself is not old but it is made up of a few different demolished house sites dating back to 1930s probably. The first demolished house I detected around, I found nothing but big aluminum junk and a few memorial pennies. I was hoping removing some big junk would unmask some things below but no luck there.
I then tried another demolished house in the corner of the park with part of foundation still visible. This time I had a little more luck with two wheat cents right next to each other and an old Yale padlock. The wheat cents are 1927 and 1940-something. Nothing earth shattering but I had fun looking for deep high tones around the house foundations.
