It is a crimp-terminated pin contact, gold-flashed on the mating surface, designed for 24-28 AWG wire.
The 24-28 AWG wire range covers the common signal wire sizes used in D-sub harnesses for serial data, I/O, and control signals. Gold flash on the contact means the wire barrel is also gold-flashed — adequate for the wire range, but the crimp quality, not the plating, determines the connection reliability.
