Well, they aren't in business and their quality was always very good. Someone might consider them collectible...
I agree, they will make a great display. If I had that kind of room I would do just that. I hate to put them out in the weather.You may want to consider using them as shelves or something creative in your bee room/honey house. As hives, they will eventually deteriorate. As furniture, you will have them for a long time.
