1 Solidus In the name of Heraclius and Heraclius Constantine; Cross with flat ends; equal busts with unbroken legend

(en) The exact date-range of these pieces is not certain. For the beginning date, many sources list 610, since that was when Heraclius came into power; however, Heraclius Constantine was only born in 612 (he was Heraclius's son). Some sources say this coin was struck after 616, but seeing as how Heraclius Constantine has a mustache, it was probably much later than that (around 629 would make the most sense).

After Heraclius died in 641, Heraclius Constantine took over, ruling for only a couple months. While some sources list 641 as the end date, Heraclius seems younger in the portrait, meaning the original coin was most likely struck before that date. Even so, this is an imitation of a real coin, so it could have been struck anytime after 641. It is unlikely this coin was struck after 796, since that is around when Franks conquered the Avars, so that is the most likely end-date.
