The brown saddle is a Challenge Event from 1996 b/c that's when they put the Olympic stamps on the Miller saddles. I was going to say $400-$450 because it's far more rare than a Sr. Event, it's a wool flocked model, and the older Collegiate saddles are worth more than the last ones. But saddles are slow selling so maybe $300. $200 is insultingly low, and kids on horse boards always underprice saddles to be in the ballpark of what they maybe can afford. ;-D If it just has a 4 digit number on it, it's a wide tree and worth more than a regular. The regulars are marked ART plus a 4 digit number. You can google to find the model number.
The dressage saddle, as I answered elsewhere, is Collegiate Baron, copy of Kieffer Wein. Maybe $300 for it? I don't know. Their dressage saddles are nice but don't fetch big prices.
