Well, when I take off my trifocals and hold it real close to my eyes, I see 3011. But then again, they don't call me Senex Caecilius (blind old man) for nothing.
I love the coin! - and I agree about not removing the number. It adds a certain mysterious provenance. Things could be worse. At one point it was also considered acceptable to counterstamp coins in museum collections, presumably so they would be less attractive to thieves. Ink can be removed, a counterstamp not so much... Roman Empire, Anonymous, Domitian to Antoninus Pius AE Quadrans, 3.25g, Rome mint: AD 81-161 Obv.: Diademed and draped bust of Venus right. Rev.: Dove standing right, S-C. Reference: RIC II 24 (p. 218) Notes: Countermark "AU" in field above dove, possibly from a university collection.
I certainly hope this is a university collection rather than overgrading gone wild. The sad part to me is that it was done when the university believed that there would never be a time they would not want to keep their coin collection. I assume they sold off the coins and bought new uniforms for the football team or something equally more important than Classical education.
Germanicus was an interesting Roman. He could have been next in line for Emperor if he hadn't died. Also he is considered one of the top 10 Roman generals. I own a few bronze coins of his.
