Coin Tumbler

Ok Wheezy I know exactly what you mean now. I do not put my valued coins in there because I do figure it will decrease the value. I know exactly where you're coming from. And I did note in my post that they were different coins lol it's because I had some that were already cleaned and some that I just recently dug up. Next time I will take a picture of the 1969 D after it is cleaned sorry about that mix up. Also it does seem to have a somewhat "granined look to the coin after it is cleaned. Now it could just be me but I think if you take a magnifying glass or what not up to the coin, you will see tiny tiny grains on the coin. Although, I might just have to put the coins in longer than I already do I'm not sure yet I'm still experimenting with it.

For Nic=> With a combination of water, aquarium rocks or other "cleaning" rocks, some sort of soap or detergent, and sometimes a little bit of powdered bleach you can make a huge difference in your coins' appearance. The rocks act as if the coins were at a beach for several years at a time and mimics the erosion affect of the water and sand at the beach on the rocks. Of course, it speeds up this "beach" effect and you can get your coins cleaned what I like to call "naturally" in about 24 hours or less. Hope this helps!

I was under the impression that this was done for modern coins found detecting so that they are made suitable for spending. Not sure if the energy input would make it worthwhile to do this for a penny though, unless doing many coins at once is available?

thanks metaldetectingtaylor for the info, I see it now, yes that would be very effective in cleaning buried and dirty coins, as well as rocks. I'm very tempted to get one, not for my coins since I source from dealers and friends & not from the ground.
