Need to know the model type to answer.
10-1000 USD depending on specifics.
25-75 USD
Colt Model 1877 "Lightning" Double Action Revolver in caliber .38 Colt and the similar revolver model "Thunderer" in caliber .41 Colt.
It depends on the make and model. Is it a double action or single action revolver?
Blue Book of Gun Values
colt made single action revolvers in 1884. Do you mean 1984 ????
Would need a model name to answer.
Double action revolver
if double action revolver it was probably made about 1923
the 'victor double action' series of revolver were marketed as a direct competitor to Iver Johnson's u.s. revolver co. double action (1910-1935).
Assuming it is .38 caliber and therefore a J-frame, and without knowing condition, $150-$300
value depends on overall condition, however, the rosco has little value...........
