I have a website with ancient coins for sale: http://augustuscoins.com/index.html It has a selection of Greek, Roman, and Byzantine coins, with a few Crusader coins on the Byzantine page. Recently I have added some coins including nice but inexpensive Constantinian pieces, coins of Nisibis in Mespotamia, and numerous Byzantine AE. and many others. A rare Honorius, a common Arcadius AE2, and many other coins. I also offer some major books here: http://augustuscoins.com/numislit.html including Books!
