Back in 1996 the Hamilton collection was a pretty big thing for collectors in general i suppose and for old ladies specifically. Anyway, they released several series of Star Wars themed plates and one of those series was the Vehicles and Vessels collection. There were 12 in all and one of them was the Millennium Falcon. (I have 10 of them and still need to try to track down Jabba’s Sail Barge and the Death Star for a reasonable price.)

Yeah I have all 12 of these and had great difficulty in getting the two you mention in the 90s but managed eventually after a lot of shouting at Hamilton as they were no help at all. I am actually trying to sell them all at the moment but most people like yourself are just looking for one or two of the plates they are missing.
Yeah, there are a lot of them on ebay. There are a couple of rare ones (the sail barge and teh deathstar) that i’d imagine would be pretty easy to sell.
I must admit that i really liked these at the time and thought that they were well worth collecting. It’s a shame that they [the Hamilton Collection] were so shaky about letting people know about the other plates in the range. 😦
