That clearly isn't your camera...
note the position of the flash holder, (your centre on auction to the left of body [looking straight on])
also notice film winder Your flat one on auction raised. (though this could be because there is film in yours or the button is just depressed).
Also Note that the lense is different, (yours is clearly neither the special nor rare 50mm lense as this projects more)...
are there any other significant marks on the camera ilke a model name or number?
even a serial number might help you discover the true value of the camera.
