I was gearing up to start a new site on Seleucid coin types when I came across this. Looks like a great database for the empire. Very easy to use showing the latest and greatest information. Looks like only Seleucus I through Antiochus III for now with the rest coming later. Also has a great map feature showing mints as well as find spots. Along with description entries there are several thousand images mostly from the ANS. Hopefully they add functionality for contributors to submit unpublished examples, which it sounds like they will. I have a bunch I can add my self. I think this pretty much kills any reason for me to continue with my own site, but it should be a good resource. The address is http://numismatics.org/sco/
