I found new site at the park the other day where a home site was located from an 1859 map. I had tried to locate the site couple times before but with no luck. I finally found it. I found an 1860 IH with a square nail hole through it along with an old pin and small gold plated ring a couple weeks ago. I found the button first and then was amazed when I dug the 1852 large cent right in the middle of the trail I was detecting along. I am looking forward to more finds here. I might post the button in another forum. It had a pattern of dots punched in the front of it (seven around the outside in a circle, seven in a tight circle near the center, and one right in the center).
