I layered up, waited for it to get above freezing, and detected a house that is now museum / historical society. I took the Equinox 600 with stock coil and my F19 with a 5" sniper coil. I did most of the yard with the Equinox and didn't find much of anything except (except trash) other than a 1927 wheat penny. I took a break and decided to get closer to the house and some trees on the property with F19 and small coil. I checked some flower beds and found a 22 short casing, but was skunked close to the house. By the base of biggest tree on the property I got a zinc penny signal. It wasn't easy to dig next to the tree, but about 3-4 inches down was a teal colored disc. I couldn't make out any details, so I stuffed it in my bag. Maybe a foot from the first target was a copper flat button.
After I got home, I couldn't make out anything on the coin except for "al" toward the center. I soaked the coin in a 50% vinegar/water solution and started tooth picking every 30 minutes or so. After about 30 minutes I could see "Half Cent" but no date yet. After another 30 minutes I could make out 18 where the date should be. After another 30 minutes I could make out that it was an 1803 or 1807. After another 30 minutes or so I finally concluded I had an 1807. I gave it about an hour more to try and get "Liberty" and "United States of America" to be visible. I decided to stop at around 3 hours, which may have been too much, but I just wanted to see more details if possible.
This is my first half cent and oldest coin for now.
