The only way to know if a unique snake is worth anything is to breed it out and see if it's a codom or recessive gene. And it actually has to make some cool combos to be a hit. There have been tons of unique looking normals that have not proven to be genetic and lots of new morphs that no one really wants to buy into because they are not that unique or don't really add much to other genes.
Personally I would never breed any animal just for the money, especially if you hate cleaning up after the animals. You really have to have a passion for the animals to be a breeder. I think you made the right decision for both yourself and the animals involved.
This reminds me of a recent post that some guy made of his 25 year old ball python. Turns out his 'pet' was actually an Enchi! Man he could have made some big money from that snake if he was a breeder 25 years ago!
