I have some high grade tetrarchal and Constantinian era (early 4th century AD) AE3 coins for sale here: http://augustusmath.hypermart.net/Tetrarchy.html under Licinius, Constantine, Crispus, Constantine II, etc. See the site for shipping costs. Licinius. Lovely silvering and green patina. Details on my site. [$35] Constantine, lovely color and surfaces. [$33] Crispus, super detail and just gorgeous. [$39] Many more excellent campgates, and many other late Roman AE are on that page (and there are other series on other linked pages). If you are interested in ancient coins or coin books, please bookmark my site. It will take you quite a while to see it all, and I add coins every few days (and less often books) .
