Can Anyone Help ID Some Ancients?

Hi all...

First time poster here. This is a neat site you have here. I've been referred to post here by SuperDave from a thread I started over at the ArsTechnica forums seeking advice on a few ancients that I found.

I was rummaging through some boxes last week and stumbled across my old coin collection. A lot of it was passed down from my great-grandfather and some other family members. A lot of the collection is turn of the century European and Asian coins, but I ran across some other coins that always intrigued me.

I've done some googling, and have been able to turn up some info on similar ancient coins (particularly, the coins in the lucite block below), but I haven't been able to turn up any info specifically on what I have here.

So, I'm curious if anyone here might be able to shed some light on these? I'd really just like to know what I have and if they might be real. I have no idea of their value, though if it turns out they're worth something, I wouldn't mind knowing so I can do something to properly store them.

A trip to a coin shop would be in order at some point, but I thought I'd see if I could get some basic info on them first.

The first six coins are loose, and the remaining coins are encased in a Lucite (or something similar) block with some labeling indicating Roman origin.

Coin #2:


Coin #3:

Coin #12 & 13:


Thanks in advance for any info :)
