How much is she worth?

most likely about 1000 to 1500 because she is still green and is not completely trained yet i would wait if you can and train her to do more things like side ping and collection. plus, i would start to train her into a pacific sport like barrel racing so you could sell her to someone who would be doing that sport. that will bring her price up. but i would also want to wait for the economy to go back up that way you can sell her for more to. but good luck
