Alrighty then. Sold most recently 1:1 for moon lucky shot - 8.4 pure. Previous sale was for 5.5? 1:1 with a GE tower. But that seller also had an offer of a moon lucky shot by a DIFFERENT seller. He also had an offer of 7.1 that was rejected. So the sale for the GE tower is clearly an outlier.

With two different offers on two different trades of a moon lucky shot, I'd say a flat price of 8.4 is reasonable.
