I understand why you asked
It can be difficult to judge, especially since your pony has such visible symbols. I don't think the hair cut looks too bad, I guess it depends on who is buying and how much that flaw matters to them. Both your pony and yum yum's pony have good and bad things about them, so it's all down to the buyer.
I'd suggest taking offers on her
but I think no less than $300.
