It's definitely sell-able! Someone should love it if the price is right, which, unfortunately, I can't help you with. I have no idea. I've seen people here say their baby quilts are worth $300+ but I have no acquaintances who would pay that for one.
Because when it all comes down to it, something is worth what others will pay, not what the books or appraisers say it is worth.
It is really cute!
