14 Keys

(Also note that the seller wants to do 16 keys)

I know that selling=/=sold, but when there are people selling/wanting lower than 17, why make 17 the high range?

14 is the low range, because the lowest recorded sale was 14 keys in unusual overpay.

16 is the high range, because the highest recorded sale was 16 keys in unusual overpay.

Feedback is much appreciated.

I'd like to thank Chigga for inspiring me to make this suggestion, and Pyroman for some, if not most, of the proof.
