I think mine (from PCB Pool) was similar.  Note that that's a very thin gold alloy, picked for improving solderability.  It's not the thick hard gold plating you want for edge connectors.

If memory serves, PCB Pool offered either "hot air leveled tin" or gold alloy plating for the traces.  The latter is better for small parts because it's flatter, and the price was either the same or close enough.
