Impossible to value with only the serial number and no other information.
Serial number of a firearm is only one factor, and probably not the most important factor. The condition of the gun is at least as important. You would need to have it inspected by an appraiser to know what it is worth.
No way to tell. The serial number does not tell make, model, and condition.
Yes it is illegal to own a gun that does not have a serial number. It is also illegal to remove the serial number off a gun.

50-150 USD
There is no set price. Rifles and shotguns made before 1968 were not required to HAVE serial numbers. I have several dozen in my collection, and not having a SN does not add to the value. However, REMOVING a serial number from a gun is worth 10 years in prison.
With just the serial number, nothing.
It would be almost impossible to identify a gun just by its serial number.
Please state the guage and condition of the gun
