I'm amazed how you people come across these cameras and have no clue about them then post a bunch of pictures that tell very little or nothing that helps identify them. Your pictures barely show enough to identify the camera. Then there's the image hosting site they're on, it keeps resizing them to match the zoom setting of the browser, bad, very bad, and the insertion of various unrelated photos and ads is unacceptable. Was that you crashed out on the couch with the box of chicken wings on the table next to the couch? You don't have to answer.
Now for the important stuff.
I can just make out 5x7 and Anastigmat on the lens. What else is printed on the lens?
What is printed on the bottom rim of the shutter? Several companies made a shutter of this design in the early 1900's.
The camera is a Seneca or was made by Seneca for another company. The back does not match any in the linked list but all the hardware and other aspects match. I believe it to be a Seneca View 1901-1905 or a Seneca View, New and Improved Variation 1 1904-1925.

The ID plate is missing off the base of the front standard. The top lens board retainer is on upside down.
The camera appears to be a 5x7. Measure the ground glass, it will be close to the film format size. There is some minor damage to the rail at the hinge. It will subtract from the value some but is not determental to the camera. The extension rail is missing which is very common.
To test the bellows for light tightness Remove the camera back and leave the lens board in place. To remove the camera back lift up on the brass pieces at the top sides of the rear standard with your thumbs to where they clear the pins on the back frame while supporting the back frame with your fingers and rotate the back frame out from the rear standard then lift out of the bottom pin holders. Open the rail as you have in your pictures and extend the front standard to the end of the rails. Now put a 40 watt appliance bulb in a portable lamp, a 15W CFL will work also. Take the camera and lamp into a totally dark room, your darkroom for film processing is best if you have one, turn off the room lights and once your eyes have adjusted turn the portable lamp on and insert it into the rear of the camera being careful not to touch the inside of the camera or bellows with the light bulb. With the light inside carefully inspect the outside of the bellows for anything other than total blackness. Anything other than black is a light leak. Move the light slowly toward the front standard and check the full length of the bellows. Having the extension rail would be helpful for light leak checking as many bellows weak points will not show up until the bellows are at or near their limit.
Value? $200 to $400 as it sits.
