Nickel + Electroless Gold.
 
Electroless Nickel/Immersion Gold, used for surface mount/LCD's/keypads/wire bonding etc. The finish normally comprises of approximately 5 microns of electroless Nickel with a very thin topcoat of Gold in the order of 0.05-0.1 micron thick. 

Although it is possible to have a plain electroless gold finish without the nickel layer, its rarely used as the rapid migration between the two metals results in a finish that quickly becomes very hard to solder.  

Price wise it is more expensive to use than HASL of silver, which tends to mean that it is most widely used for key pads or when LCD's are directly mounted onto the circuit board.
