I collect tokens but not theses - in my opinion the Token Catalog site won't help you much - although it is a fantastic site you don't see values. I would look on
ebay to see what these are selling for.
As to your question about selling them together - I would say that is the easiest way - sell as a lot - you might get more if you spent time to research and market each one but if you have no interest why bother.
This is a narrow field of collector and if you can find the right one one
ebay you can do ok - perhaps list at a high price and see what happens.
