I just listed for sale AE coins of Gratian (AD 367-383): http://augustuscoins.com/Valentinian.html including some types that are rarely seen but inexpensive anyway and some that are top grade for type. AE3 Super for type [$49] AE2 lovely glossy black patina [$39] There are also ten other coins of Gratian, and that page also has a good selection of coins of Theodosius and other late Roman emperors. See the page for inexpensive shipping costs. Late Roman AE is fun to collect because you can get a remarkably fine group on a limited budget. Check out my educational site to see all the types and find out about them. http://augustuscoins.com/ed/ricix/
