What is the value of a colt serpentine series set of revolvers?

Most go for 800-1200 depending on year and of course condition because they were discontinued in 1999 with a pretty limited run. Many collectors keep their Anacondas for years before even thinking of selling them. They are considered rather rare. If you found one for 300 dollars like the answer before then you would have to buy it immediately and sell it for 900. 300 is very unlikely. Even 700 is a great deal. BAck in 1994 it would go for 500 but in 2010 it is most likely going to cost you about a 1000.
