1877 if it's a Single Action Army. Nothing special about the serial number.
there are far to many #s to be a proper serial #
this question should be under Colt Firearms section
if double action revolver it was probably made about 1923
Don't know value, but made in 1926.
No serial number data published.
I found a Colt army special with that serial number being made about 1916.Don.t know the value though it would depend on it's condition.
