If it letters as leaving Colt that way, quite a bit. You are in the 500-1500 range
$250.
what is a 1978 .38 special colt cobra serial #m52453 nickel plated with pearl handle worth?
A Colt Cobra 38 Special nickel plated would be worth between $200-$350. Of course condition to make or break any "price". Other factors would be original box with all papers, and if any alterations were made including grips, generic nickel plating, etc. I have seen some 70's Colts and Smiths, (snubbies), that would be lucky to fetch $50 due to condition, and some that are virtually "new old stock", in the box never touched like it left the factory bring $400.
Depends on condition, box, accessories, papers, etc. Range from 100-1000 USD
Don't know the value, but Serial numbers B83551 - B99999 were made in 1972.
$6,573.68
about $250
When Davis arms went out of business Cobra Pistols bought their equipment and continued to make Derringers under their name. I believe all the parts are interchangeable, See link below for Cobra pistols.
