<p>[QUOTE="Valentinian, post: 3540804, member: 44316"]The OP coin is an overstrike of Heraclius (610-641) and son, as [USER=72790]@kevin McGonigal[/USER] noted. There is a way to try to determine the undertype if you can see any of it. Byzantine AE coin strikes almost always have die-axis 6:00 (like a US quarter). That means if you can find any of the undertype and put that upright and flip it top-to-bottom, the other side will be upright and you can look for remaining details is the right places with the correct orientation.</p><p><br /></p><p>Let's try that with the OP coin. The reverse seems easier to begin with. The overtype has M and ANNO down its left, with Δ for officina and CON below. This is Sear 805.

Then I think I see a cross (+) above a rounded M (<font size="6">m</font>). Rounded m's are used by the previous emperors Phocas (602-61), Maurice (582-602), but only at Antioch and overstrikes are usually on coins of the same mint, and Tiberius II (578-582). Flip it over using that axis and expect the top of the other side to be upright (which will be in the same orientation in the second picture if you a reading this, that is, look at it as if the top were 11:00.) I can't make out much--maybe ON STAN 10:30 - 1:30? That must be wrong. I looked in Dumbarton Oaks and did not find Tiberius II Constantine with that legend split, and it would not be Phocas (FOCAS on his coins). </p><p><br /></p><p>So, I can't make out the undertype.
