Thanks all...I was thinking maybe a leather brush...idk, can't seem to find anything like it on the Internet.
We went back for a little while again and found 4 more coins and a 70's type Hotwheel. It was missing the bottom so no date.
The property was destroyed by Katrina, and has a lot of random "dings" so I'm careful not to dig on just anything. My husband lost his wedding ring here after the storm during cleanup so my ultimate goal is to find it. 7 acres and almost 11 years....nothing yet.
