I have a huge amount of pennies that I'm going through that, though they were kept pretty well, they are pretty dirty. I have been wiping them with a dry cloth, if they're dirty. Occasionally I will get a bowl of water with some dish soap and one of plain water and try to gently wash them, one at a time. My goals are to remove dust and cigarette tar, but to avoid scratching the coin.
Is this considered "cleaning"? Or is cleaning more like stripping the brown layer off a penny (thus removing any mint luster)?
Also, what is considered Polishing? Is that like using a copper polish on the coin or is it more like buffing the coin?
What should I be doing to curate this collection? The ones with cigarette tar and obvious layers of dust really bug me. Should I be leaving them alone?
