1 Sold for $2.18/ 2.34 = 0.93, ~43.44 ref.

Excluding all other sales due to them being either too low for current buy orders or too high for current sell orders. Also excluding the sales for 42.44 and 43.44 ref, as they appear to be outlier/ quicksell sales compared to rhe vast majority of sales being at least 1 key. Going with 1.2 - 1.8 keys.
