At least, that is a question I can answer.
Most of your coins do not need cleaning, with the exception of G3, which would benefit from a very long bath in olive oil. You may want to consult Bruce on the cleaning and preservation board on H5. That may be innocent oxidation, or it may be bronze disease. Maybe you should keep it separate from other coins until you know what it is.
I think it would really help asm and others if you would post the (groups of) coins individually. Alternatively, this thread could be split in individual posts...
