Need a little help with Roman Coins

[gunner45]

I picked these up the other day and I'm having trouble identifying them. I would greatly appreciate any help I could get in figuring out the ID
Thanks, Dustin

Larger coin appears to be Constantine I, as Augustus though I can't discern the mint mark.
Like this: LONDON MINT III

There are so many varieties of Roman coins out there it is very hard to ID them sometimes. Here is a site which may help you. So far it is one of the better sites for Roman coins I have found thus far.
