In the early days of Ebay, there were only a few Tolkien-related items. Now there are thousands and the only way to may Ebay manageable is to conduct good searches. You can search wide or narrow. I find the secret is discovering unique keywords that get me in the domain of items that interest me and then a set of keywords to subtract from the search so that I can cancel out a number of items I don't want in the search. Below are sets of searches I use on Ebay when trying to find things.
1. A search that includes just about everything across Ebay categories:
2. A search of autographed and signed items:
3. A search of old or vintage items:
4. A general search for all items greater than $50:
5. A search for character names without major terms. This is helpful in finding items that are described only by the character name. These items will be missed by some of the earlier searches. Sometimes these are rare vintage items (e.g. A Bilbo Surfboard):
6. A search for collectible pins:
7. A random search:
THE SWORD OF EOWYN
A very high quality, beautiful sword. This would make a great decorative gift for the shield maiden in your life, or someone who just loves equestrian design.
LORD OF THE RINGS JEWELRY
Now that the movies have largely run their merchandising course, this may be the best time to purchase high quality jewelry at discounted prices. Use these as gifts for years to come.
LORD OF THE RINGS GAMES!
It appears that any game that could possibly have a Lord of the Rings theme has been produced. These include Monopoly, Trivial Pursuit, Backgammon and Dominoes.
LORD OF THE RINGS FIGURES
Figures from the movies include a large action figure series. There are separate figure sets and color schemes for each movie. The highest quality figures were made by Sideshow WETA. Although these are expensive, they sell out quickly and will likely keep their values.
