Unfortunately, none of them are particularly valuable. Ancients dealers generally sell "unidentified Roman coins" for $5 to $10 each, and I'd have to classify the top two as "unidentified" since we haven't been able to fully identify them. And coin collectors won't really want that last one as it's considered "damaged" due to the attached loop, so it too is likely to be just a $5 to $10 coin. An antique jewellery store might pay more for that last one, as it is (apparently ) a genuine ancient coin, but I don't really know.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
