It probably isn't stamped anywhere on the gun. If you know the manufacturer and model, there may be a serial number. If there is a serial, there may be records which will give an approximate date of manufacture.
Go to the Winchester site. There used to be a link that you could follow that showed ranges of serial numbers and manufacture dates. I don't know about where to go for value. You could go to a gun store and ask for them to give you an approximate value for insurance.
