not worth this headache to find out
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.
10-1000 USD depending on specifics
50-250 usd
50 -550 usd
50-250 USd
100-400 USD
It was made in 1961 and worth can only be established by its' condition.
what is a 1978 .38 special colt cobra serial #m52453 nickel plated with pearl handle worth?
Colt has not offered a AR15 in 308
100-1000 usd
If you call Colt they will tell you when it was made.
