Reubmitting according to the counter proof recieved.

2 months old price.

All offers (or almost all) evaluated according to the value of buds at the time when offers were made. Unusual overpay included.

Proof:

Sold for 19 keys and 5 ref (~20 keys)

To sum up, I'm putting 24 keys as a high end for the precise moment, because Cowl offer is rather old and might be an outlier,

Offers around 22 keys worth are rather common to be the middle value. Low end is 20 keys, bacuse that was the lowest offer accepted according to the proof.
