Couldn't find any more sales besides storage bot trades.

Sellers starting at 40 keys

Buyers at 13, excluding oldest sale at 15.

Excluding 9 keys, below buyers.

I prefer a range when I only have marketplace sales, but couldn't find more sales for pure keys that were in reasonable range of 37.

Including 15 makes the range too big and it doesn't properly reflect the price.

Going with 37 flat.

Note that if a price moderator considers 15-37 a proper range (we've seen far worse) I'll resuggest accordingly.
