He will be joined by New Zealand captain Kane Williamson who was sold for $641,000.
Lynn went to the Kolkata Knight Riders for $2.1 million, as did pace bowling compatriot Mitchell Starc for $2m.
Australian Glenn Maxwell ($1.9m to the Delhi Daredevils), Kedar Jadhav ($1.7m to the Chennai Super Kings) and Ravichandran Ashwin ($1.6m to the Kings XI Punjab) were other big earners.
The evening held less joy for West Indian Chris Gayle, South African Hashim Amla, Englishman Joe Root, Australian James Faulkner and Indian Murali Vijay. All went unsold.
New Zealand's Martin Guptill joined their ranks, despite a relatively low reserve of $160,000 and previously stints with Kings XI Punjab and Mumbai Indians. The perception he struggles against spin in the subcontinent continues to shadow him.
In 67 T20 international innings, Guptill averages 32.56 at a strike rate of 130; in 21 T20 innings on the subcontinent he averages 20.52 at a strike rate of 113. He could still get snaffled at the back end of the auction.
