As you can tell from my username, I like Roman coins from the period of Valentinian and later. I have added ten from my collection (which has been carefully collected since 1971) at the top of this page: http://augustusmath.hypermart.net/Valentinian.html They include: Valentinian. 364-375. AE3. GLORIA ROMANORVM Emperor right drags captive and holds labarum 364-388 [RIC also lists it in the period 388-392 at Trier] 18 mm. 2.24 grams. RIC Siscia 5, page 146. Lovely even glossy black [$24] Valens. 364-378 SECVRITAS REPVBLICAE Victory advancing left holding wreath and palm. 364-378 18 mm. 2.40 grams RIC Antioch 12. Esty 6. [$19] The page has many excellent coins from this time period, including coins from mints not often seen and some rarities. Shipping cost is given on my page. It would be $2 or $3 in the US for one coin.
