Is my Austrlian Shepherd worth a lot?

If my aussie had had a litter with a male who looked just like her, people say the pupps could be worth like over 2k...is that true? She has extremely light blue eyes, almost white eyes actually, and has white front paws, a white stomach and neck, light brown back paws, light brown eyebrows, and a black head top head and back and light brown face and a white snout...She stands like a champion and is super fast and obedient. She has nice white teeth and a medium length coat. She weighs 45 lbs and stands about 28 inches from paw to head, and 28 inches from tail to nose (she has a stubby little tail) and her coat is also a teeny bit curly but is mostly straight...I want to know because we had her spayed and we regrett it since we found out how much she could be worth and we only payed like 250 for her because we were good friends with the breeder, we got her half off, and was the only puppy who kept her blues eyes (all the other puppies eyes turned brown.)
