A common method for mass producing taper pins with minimal tooling cost is by swiss machine. But given the relatively high cost of your raw material (silver wire), I can see why you might prefer some cold forming process that will minimize the amount of waste material.

What was the problem you had cold forming the pins using progressive dies? Was it a dimensional/form tolerance issue?

I wonder if it could be roll formed? Would need expensive dies (rolls) and require a second set at 90 degrees to reshape the centre plane.
