@ausmodius, that is an interesting problem to have! I do hope that those are not fakes, but we really need pictures to get a sense of what you have.
To add to @rayder's comments, take good pictures of 2 or 3 of the BEST (in the best condition) of each category-both sides, and give us the weight and dimensions of each one.
If you can see any that look like silver, take a picture of one or 2 as well. I am assuming that there is no gold here.
That will get us a good sense of the kind of collection you have.
The last thing you want to do is make a quick sale. What you might end up doing is paying a knowledgable person for an appraisal-and identify the really valuable ones, if any. If you tell us the part of the country you are in, we might be able to recommend someone.
Depending on where you live, that could be easy or difficult.
Remember, just because they are ancient coins does not make them valuable.
