Yeah, there's roughly 25% chance to get those in the Gallery of Serpents expedition.

The other possibilities (each seem to have 25% chance) provide items worth either 125 echoes, 312.5 echoes, or 60/125 echoes (which one depends on whether you are willing to advance the Liberation of Night).

Thus, average gain from that expedition is 280.625 echoes (if you're anti-Liberation) or 295.875 echoes (if you support the Revolutionaries).
