I have had my Circle Y saddle for about 15 years. I believe the person I got it from had had it since he was a kid. If that were the case it may be around 75 years old by now. I have barly ever used it since I tend to ride more English. It is time to sell it but I have no idea of the value since I can't find even one saddle that matchs it, and I have looked! Please help. Thank you
