Assuming your New Navy Model 1889 is original nickel and in the nice shape it appears, value could be as high as $2000.
Nickel is rare, and one in that high of condition would be a collectors find.
It appears to have the original heat blued trigger as original.
Treat it gently. These old guns have very delicate, intricate actions that break and get out of order easily.
There are almost no parts available and almost no gunsmith will touch one.
Colt invented the double action swing-out cylinder revolver in 1889 as the Colt New Navy Model of 1889.
In 1892 the Army bought it too, and the name was changed to the Colt New Army and Navy.
Colt put the design through a rapid series of improvements and each improvement got a new model number. These were the Models 1889, 1892, 1894, 1895, 1896, 1901, and 1903.
Production ended in 1907.
These were made as both military issue and commercial sales guns.
Original calibers were the .38 Long Colt and the .41 Long Colt.
It was the military issue model chambered in .38 Long Colt that failed in the Philippines and led to the adoption of the Colt 1911 .45 Automatic.
These are considered to be display guns today due to the availability of ammunition, and the chances of damaging the action.
They are a historic gun being the first modern revolver with a swing-out cylinder.
If all original, a collector would be very interested.
