There are quite a few of these out there.  To tell them apart, besides looking at the grade, look at whether there is filing, bending, scratching, graffiti, clipping, or another problem.  Further, look at all three faces on the coin.  Can you see all of the eyeballs?  
 
Romanos was a Byzantine noble and senior official in Constantinople when the dying Constantine VIII forced him to divorce his wife and marry the emperor's daughter Zoë. Upon Constantine's death three days later, Romanos took the throne.
Romanos has been recorded as a well-meaning but ineffective emperor. He disorganised the tax system and undermined the military, personally leading a disastrous military expedition against Aleppo. He fell out with his wife and foiled several attempts on his throne, including two which revolved around his sister-in-law Theodora. He spent large amounts on the construction and repair of churches and monasteries. He died after six years on the throne, allegedly murdered, and was succeeded by his wife's young lover, Michael IV.
