I started to follow the Guardians of the night right after they retired. I was going to put a set together but stopped about half-way through. I could not justify buying them and putting them in storage. They just took up too much room. I do have a few in the house on tables and that is what they are best at. Just having a few around the house as lighted features is great, but a full collection takes allot of room.

Since I was interested in them I have followed the GN's on eBay since they retired. The surprising thing that I noticed was that the Statue of Liberty GN018 was never on eBay.

My suspicion is that the three last GN's had a lower production number than the first 12. Remember the last three were not issued the same year as the first 12. They came over on a different boat and there is a chance they didn’t even have the same amount produced.
All the other Guardians have been on eBay and have run about from $15 to $60. The Liberty is very popular which also makes it hard to find.
