Denerii had stopped long before Helena but there are coins of hers we call AE3 or follis (plural: folles).
Nope, as Doug mentioned, they ceased to existed by her time. Helena (324 - 330 A.D) Æ3 O: FL HELENA AVGVSTA, Draped bust right. R: SECVRITAS-REIPVBLICE, Securitas standing left. Siscia Mint, 5th offcina 19mm 2.8g RIC 218
Thanks for the quick replies. Yes, the follis is the coin I was looking for. I remember seeing her on the obverse of a coin, but I thought it was a denarius. BobC
It's a abbreviation of her name-- FLavia. Here's a handy website with a searchable glossary of names, terms, and abbreviations for Roman Imperial coins: http://cointranslator.com/
You should be able to find plenty of information on LRBs (Late Roman Bronzes) on line (http://www.lateromanbronzecoinforum.com/). If you want a sliver looking coin, there are silvered coins, but they can be pricey. I found over 500 Helena Aug coins on acsearch.info (history) and over 50 on vcoins.com (coins for sale). I saw a really good bronze for less than $50. If you have deep pockets, you could go for the gold:
Helena in gold would be nice, but, well, maybe another day .... Helena, AE3 Heraclea mint, 5th officina FL HELENA AVGVSTA, draped and diademed bust right SECVRITAS REIPVBLICE, Helena standing left, holding branch and raising her dress. dot SMHE dot at exergue 2.9 gr Ref : Cohen # 12, LRBC # 879 Q
There are also smaller coins depicting her, issued by her three grandchildren after Constantine's death. Helena had been dead for about 8 years when these were issued: Helena, Augusta AD 324-228/30. Roman billon reduced centenionalis; 1.24 g, 13.4 mm. Trier, AD 337-340. Obv: FL IVL HELENAE AVG, diademed and draped bust, right.
