I have hundreds of Constantine area coins wich I have not ID because they are very hard for me most of the legands are just partial and they all seem to look the same. One day I will have to get down and dirty to ID them.
David,
Worse than that, some of the emperors of that era appear in multiple volumes of
RIC 
However, if there is a silver lining, it is that once you get through that batch you should be much better at
attribution.
One thing I like to do is browse through the "
recent additions" section of
FORVM where you can mouse over the coin to get the emperor name and other information. I'm actually getting pretty
good at IDing the emperor before mousing over. It's a nice little exercise for your eyes and brain!
