What is the value of a 1955 Gibson Royaltone?

[Jack Hanson]

I am considering putting my '55 Royaltone up for sale. Anyone have any idea what it's worth? Excellent condition in its original case (missing handle). Only 67 shipped between 1955 and 1959, per Gibson Electric Steel Guitars 1935 - 1967 by Andre Duchossoir. Apples vs oranges, but in comparison to 1959 Les Paul Standards (643 produced), Royaltones are scarce, if not rare. If anyone has any interest, please send a P.M.
