Thanks for pointing this out as I actually have one on the way to me. It's a Germanicus as struck under Claudius, but of the Rome mint, I believe.
LOL, monster bronze brockage! They had to work hard to pound THAT one out! Great coin, nice find... now I gotta git one!
Yup, those Frank Robinson auction pics are pretty much devoid of colour, so the pleasant toning on this one came as a surprise. FSR auction pics: The CNG pics from 2003 show some hints of colour, but not much: They're are not especially pronounced, but light iridescence on toned silver is always gravy to me .
