Winnie, very difficult to say! On some blades, the KISSAKI (blade tip) is damaged. This is a considerable value loss as this cannot be 'repaired' by an amateur. This applies as well to your blades' condition in general, so it is not possible to give a reliable evaluation by photos alone. Stephen has given you a realistic general idea of what you can expect when you sell on a non-expert market. Some blades, if traditionally forged, might achieve double or triple of that (or more) in good condition. Please compare by looking here at NBM, what a desirable condition can look like. Another way could be to have an expert have a closer look at your blades. This could probably be done at a sword show or exhibition.
