Mamiya RB67 worth?

[cka]

I have a Mamiya RB67 camera with by WordShark"> attachments that are in amazing condition. I also have some other pieces. The Roll Holder seen in the photo, I have 6 of those with boxes. I want to sell the whole collection as a lot, but not sure what it is worth. Can anyone give me an idea of what I should sell it for?

Thank you in advance.

The camera has a value of $600-$900 w/normal 90mm ~ f/3.8 lens.
The Roll Holder(s) have a value of $150-$300 per holder (although
I am not sure of the film size it holds). This camera also had
a available Polaroid back as well.
