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 mint
Sear 75

Dear CW

Actually the first one of the second group is not the extemely rare Sear 714 
It is Sear 872, Heraclius half follis Carthage mint.
Here is a better example.
(PS It is not clear on Okejos coin, but if Heraclius is bearded-which I do not think-then it is Sear 874)
