You may be aware there are about 20 variations of the Victory reverse coins in your collection. To differentiate each Victory
('victoriaoav') coin to its specific attribution will take more than a casual review. There are members here, like CRU and his dad, who are extremely knowledgeable about Roman coins. If the Roman silver coins would be presented in highly focused obverse and reverse pics (say) in twos versus the entire collection, you may get a more specific answer to your questions.

PS: I like the collection and would also like to know the backstory as to how they came into your possession.
