How much is a daisy red Ryder BB gun 50th anniversry?

One of the most important items in determining the value of antique air guns is the current condition of the Rifle along with it's collect-ability or demand. So it is not possible to give you an estimate of value with out some sort of description to the current condition of the Daisy. I can tell you this. It was produced in 1988 and carries a 50 year warranty. (Number 1938 B 50th Anniversary)
