I am not an appraiser but my estimate (as someone who as been around horses and a lot of saddles) would be around $600 a piece. I actually like the Billy Cook the best as a using saddle, but the parade saddle is in really nice shape. It doesn't look like real silver, only "dots" but it sure is beautiful and in nice condition. Maybe someone else can chime in as well. I certainly wouldn't take any less that $500 each (unless you really need to sell them) but I don't know how much over
$600 they would bring either.
If you ask slightly higher than you will take, you have a little wiggle room for bargaining.
