Need help with cleaning coins

[Willieg]

I'm new to metal detecting and I have found some old penny's. One of them I can see 1910. They have a layer of crime on on them and I don't want to mess them up. Thanks guy's

The other one is very thin and can barely tell it's a penny.

If it was covered in green crust a month in EVO or longer might have worked. With a coin in that condition, I normally try to pick it clean with toothpicks and a mounted magnifying glass. You might want to get a set of Andre's pencils

What is EVO?

Give it the "tater treatment", stick it in a potato and let sit for 24 hours.
Take it out, rinse and wipe clean, repeat as necessary.

Chemicals in potatoes clean gunk very good, but of course some coins are hopeless.

evo = extra virgin olive oil
