Pondering What Roman Type To Collect......

Now that I've started collecting ancient coins I find that, as usual, I'm all over the place.

I have about a dozen fairly nice coins, mostly Roman , some Greek, and about a dozen uncleaned coins soaking in distilled water, that don't seem to have much hope.

I haven't spent much, but enough where I could of had a couple of nice coins for a type collection. I don't regret having the coins, I like them and it's been interesting and fun.

I am wondering if collecting a group of Constantine commemoratives would be a good idea. One each from different mints and the officinas. Like this one, I borrowed the picture from Wildwinds.



For some reason I like these coins and there seem to be quite a few around in nice condition for reasonable prices.

I'm interested in knowing what some of you think about a set like this. Would it be a good way to go while I continue studying ancients or would it be better to wait and find another type?

There are so many you could choose from.

Any opinions will be appreciated.

Once again ....Thanks
