Crescent made inexpensive "working" firearms 70-100 yrs ago
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.

@ turn of the century plus or minus a few decades
Empire Arms was a trade name sold by Sears Roebuck. If it has the Crescent name on it, it would date from about 1893 to 1930. If it has open hammers and damascus barrels, it is more likely to be an early gun. Hammerless guns and fluid steel barrels were introduced about 1907, but sidehammer guns were not discontinued.
Early 1900's, from 1900-1920 or thereabouts. Value depends on condition. Low of $20 for a parts gun, high of $100 for top condition. sales@countrygunsmith.net
