Buyer for 16 keys:

All sales went pretty fast, Baconator sold his Chief for 18 keys pure in 3 days, and then Lamarr sold id for 23 keys mixed

I sold mine in 4 days for 20 keys pure. I think not necessary to keep sales at 17 and 18 in range due mane sales in 20-25 range and buyers for 16 and 19 (gone)
