Team, Here is a handful (20-30, really haven't counted them) of ancient Roman/Greek coins I've had soaking in olive oil for the past few months. Think this afternoon would be a good time to start cleaning and IDing them. From what I can tell they are all copper or bronze and vary greatly in size. The olive oil didn't cause the grime to flake off like I thought it would but I haven't started aggressively cleaning them yet. Take Care Ben
