How much would you expect to spend for a Dash Ta Fame filly at an auction?  I am trying to be realistic before registering to bid at some of these auctions coming up.

Depends how she's bred on the rest of the papers, I'm assuming we're talking an actual DTF daughter? Unbroke? Thats going to make a huge difference, as well as which auction. Weanlings will probably start around $20K and go up from there. If she's nice bred on the rest of her papers and riding, you're probably $30-40K. Again, depends on the specifics of the filly & auction. I've seen them all over the map but young fillies are $$$$

Like already said, the bottomside of the papers means a lot. But as a rule of thumb I would think a filly whos young and sound to continue training and breed would be 20k minimum, with value increases several fold if out of a proven momma
