Two sites are particularly handy for both beginning and advanced collectors: www.catbikes.ch (then to 'pages for Roman coin collectors') and you can download all files you need. A second good site is www.Wildwinds.com

Welcome to the board where there are a lot of your countrymen

The second coin is of the Constantinian dynasty, looks like Constantine II to me Siscia mint, for the particulars go to the Wildwinds site previously mentioned, I have found it invalueable, although it is an incomplete reference most coins can be identified there.

Thanks a lot folks. I can get pretty far but still have doubts about the final determination. Within categories there seems to be a lot of variation. I am new to it so it will take some time!
