There are a lot of factors that go into pricing. Age, sex, size, combo, hets, what its feeding on and feeding response, and most importantly the quality of the genes that it is carrying.
Is there a certain animal that you are trying to price out?
If a snake is worth $1600 to you by all means price it as such. These are living breathing animals that have value. Be patient, screen your buyers, and the right person who values that animal just as much as you do will come along.
