Your Top one in the second picture is Sear 714 I believe
“Revolt of the Heraclii” Carthage
mint 608-610 AD
Nice Find if it is. I cordially mention if it is it is a rather rare
coin but in your case it looks like it has been badly cleaned and hence greatly diminished in value. I know for myself that I struggle with patience but have found over time when after finding a coin like this that the original patina
iwould have been worth the extra time it took to clean. I comment on this only that it has been a struggle for me to learn and hence I pass it on.
Your second coin is a Justin I Pentanummium Constantinople
