value depends on overall condition. if your colt is a police positive special, made about 1921
Proofhouse.com has Colt sn tables.
The age would be around 1949.
Don't know value, but made about 1913 for police positive special
Does the serial number have a D before the numbers. If it does, it is made in 1966. The Colt Police Positive Special was made in large numbers, therefore reducing the value. I have seen prices from $200-400 depending on the condition. Mark Brown
