I wish I had a few extra bucks I would be all over some of them! Something I noticed though is the way it is listed, its in the category "Collectibles, then Trading Cards. I think this might be contributing to a lower bid activity. There are two areas where most cards are found and they are listed in the lesser viewed area now.
If they are listed under the category Toys and Hobbies, Trading Cards, then Lord of the Rings it might get a few more hits next time! Under this category it has its own section and has a lot more cards listed and searched for here.
I could be wrong but I think it would get more hits this way. If I go to eBay and pull up the LOTR category under toys and hobbies, and search for items ending soonest its not there! This means that a lot of people looking for these cards might not be seeing your listings.
I just noticed this and thought you might be interested, hope they get some more hits soon and good luck!
