Not just more cost-efficient; also more combat-efficient. Silver being as soft as it is (even if layered over steel); the blade would wear down quickly if used for every battle. That means that most likely, sooner or later the weapon would be left blunt in battle against humans or, possibly worse, the silver layering could wear away leaving the witcher with nothing but a simple steel sword while fighting something particularly nasty, like a manticore or black dragon.
