Don`t know about that !! Try just telling them the same thing you told us,, that you are thinking about trading it and don`t want to get ripped off !! I bet someone would give you a general idea of what would be fair !! You don`t have to bluntly say "whats the value" !! That's probably what they have a problem with !! Just apologize ahead of time in case you do something wrong !! I really don`t know their rules but I have used the site in researching other clocks and watches !!
