34, 60, 21, 65, 60, 80, 61, 58, 58, 60

Sales but ordered

21, 34, 58, 58, 60, 60, 60, 61, 65, 80

Given that 34 was to buyers, and 21 is below buyers.

Running with 58 - 80 keys here

Thanks Fish:

A lot of the sub 80 sales are recent too though. pks at ~60 on May 7th and April 28th

Taking 58 – 65 instead
