Welcome Newbie123,
That over and under, rotating barreled combination Ball and Shotgun is quite fascinating and obviously well made and cared for. Without any markings I can see in the pictures, I would say it was made (rather than manufactured) by a good gunsmith probably in the early 1800's for hunting purposes in possibly Switzerland/Austria/Germany or possibly further east in Europe.
If there are Proof Marks that at least should identify the country of origin, a makers name (if there is one) may also assist.
As to it's value, it looks good enough to grace a museum so it will be of interest to serious firearms collectors and therefore bring a very good price. However, this double is way outside my own area of experience or expertese and would simply be guessing at a price, which is not what you really want. What is the seller asking for it?
You should expect more replies later today once America wakes up.
Harry
