I have a complete set of the Known World Gazetteer series, including the boxed set and the trail maps.  The Books are in various condition, some I broke the shrink on and it really good shape, others (like GAZ 1) are more worn.  

Would I be better served by bundling this into a lot, or selling off in pieces?

definitely not as a lot... maybe you could group them (3/4 gaz per auction) but the best solution is a single item auction for each of them!

I would probably only group them together if they are very worn.  Most people are only looking for a couple of them and by themselves they probably normally sell between $15 - $50 depending on condiiton and which ones you have.
