Being 9, she is young enough for you to campaign her for a couple of years and see if she will stand out. If she does, then when the market turns around, you will be confident and have a track record justifying her breedability... Bloodlines are important, but also conformation, temperament, and very importantly performance record. If your mare is competing and winning in your area, you will be more likely to have people drooling over the possibility of her foals.
People in my area LOVED my stallion, and I have shown him heavily from age 3 to present (age 6), but with our current market, I decided to geld him (after 1 gorgeous colt that we are keeping and gelding), because he is much more marketable as a lesson horse or horse for a kid to lease than he is as a breeding stallion because of the lack of breeding/young horse purchase in our area and the current market.
We have a mare with bloodlines that I personally LOVE, and I DO want to breed her again (she is the one who had the colt by my APHA stud), but I want to spend a few years finishing her training and competing on her (she is gorgeous and has a lot of talent) before breeding her again. When we breed her again, we will take our time to find a great stud, and keep the foal.
I just wanted to share my own personal epiphanies about breeding...I don't regret anything I have done, but my thinking has just evolved as I have seen where the breeding market for horses is at.
Good luck with your decision...take your time making them (picking the right stud, when to breed, etc.)
