how much is it worth
What information would you want? Crescent made single shotguns from 1893 to 1930. If it has a large side hammer and damascus barrels, it would almost certainly be from before 1915. If it has fluid steel barrels and a center hammer (or is hammerless) then sometime after 1903.
From the 2002 Standard Catalog of Firearms: In 1905 Crescent's first hammerless sidelock was introduced as the American Gun Co. "Knickerbocker" Model No. 6. This very popular model became the Crescent "Peerless" No. 6 in 1922. In 1928 it became the Crescent "Empire" No. 60. and in 1931 the Crescent-Davis "New Empire" No. 88, "New Empire" No. 9, and "Empire" No. 9.

We just bought a Crescent Firearms 20 gauge single shot at an auction in Walterboro, SC (outside Charleston) for $95 and from what I understand, it's not worth any more than that in great shape. I've done some research online about it and looks as though you will only be able to get parts made by a good gunsmith. The parts are no longer available.
Crescent firearms were made from 1892 to 1932.
