~9.5 keys

So it seems the first sale would be a dump somewhere between 9 and 10 -> unknown sale (higher) -> 10 key dump -> 11 keys -> low dump -> 9.5 keys

Going with 9.5 - 10 keys given two potential sales at that, and we know that one of the sales was for sure ~10. Going to exclude 11 given it was dumped.
