Turn Detector On - Sweep Coil - Dig High Tones

[RD3D]

Once again my CZ-3D amazes me! NASA Tom should win some type of award for inventing the 3D!!! I detected an old church park area which was hit by plenty of detectorists over many many years. All were deep high tone signals and very closely co-located to iron/trash. I used the standard 8" coil and will go back to the site with the 5". Not shown in the pictures are 1918s, 1919 & 1952D wheat pennies and a 1852 Large Cent.

You're right. The 3D is a simple but powerful machine. That's why I am glad it was my 1st high-end machine. I won't part with it.

Now, lets see a pic of that Large Cent too. I've only found 1 of them and it's very high on my list of favorite finds.

1852 Large Cent before cleaning. Any copper cleaning suggestions?

All I've ever heard is to soak it in olive oil. Might take weeks to work, but it the gentlest method. If you plan on selling, maybe as-found is best.

Just about anything beyond a toothbrush, water and soap will tear it up. Soaking in lemon juice will make it pink, more visible but pink. Boiling in peroxide will make it black. Boiling in peroxide and scrubbing with a brass bristle brush will knock the pits out and make it look rough but shiny. Obviously I've tried all of these. I tried them on IHs. Mostly I just do toothbrush, water and gel toothpaste. Baking soda on a wet toothbrush might do Ok. Good luck with whatever you try.
