A Colt 1908 hammerless .25 with that serial number was made in 1914.
It sounds to me that you have a Model 1908 hammerless model in .25cal.your serial number would indicate that this pistol was made in the year 1919.
about 1920 the value would depend of overall condition of pistol.
about 1920
if it's a 380 caliber then made about 1924
your colt 25 cal semi-auto was made in 1972.
