I just put these on the main page of my site: http://augustuscoins.com/index.html One is a rare AE4 coin of Valentinian III and the other a rare denomination of Justinian: Valentinian III, 425-435 13 mm. 1.41 grams. VOT/XX RIC X 2130 Very rare. Good portrait. Good surfaces. This coin, $125 + shipping. Justinian, 527-565. Rare denomination: 4-nummia, Delta. Large Δ 14-12 mm. Delta. A and P either side. Sear 194-5. [$135+$4 in the US] Look around to find other examples and you will see just how rare they are. Then come back and consider these again.
