Nice coin, I like these Type II Nero's ..
"Type II
Coins minted between 54 and 58 CE fall into the second type of Neronian portraiture. Type II coins still display the helmet style of hair yet now depict a more mature teenager."
I always wanna buy these because they are very affordable and great designs and metal, but.. then when I get them, they are to small! I generally stay clear, the last one I got was a Alexander iii obol to add to the collection.
