I don't really have any valuable ponies - I think my Italians or UK exclusives would go for a little more than my regular ponies. My favourite pony is Gusty - and my favourite version is Italian Gusty. I did used to have a Brazilian Baby Gusty, she was my most valuable pony and my favourite at the time. But I've had ponies worth more than Gusty come and go, and she's still my favourite.
